SAITAMA, JP / ACCESS Newswire / August 4, 2026 / With over 70 years of accumulated manufacturing technology and a world-leading market share in the NTC thermistor field, Shibaura Electronics supports a variety of technologies essential to modern society from the perspective of temperature sensing.
Temperature Sensing
As electric vehicles, smart buildings, and automated manufacturing sites transform the landscape of the global economy, temperature sensing is becoming increasingly important as a fundamental technology supporting their reliability. Shibaura Electronics Co., Ltd., established in 1953, is a Japanese manufacturer that has been refining its technology in this field for over 70 years.
The company handles temperature sensing components that are central to a wide range of products, including EV battery systems, air conditioners, medical equipment, and industrial equipment, and holds the world’s top market share in the NTC thermistor field.
Shibaura Electronics’ NTC thermistors are incorporated into products used daily by people all over the world. Temperature is a critical factor in determining the performance, safety, and reliability of electronic and mechanical systems. Cooling systems react before EV batteries overheat. Refrigerators detect temperature changes before food quality is affected. Industrial furnaces maintain accurate temperatures over long periods. Behind all of this operation lies the presence of temperature sensors manufactured with high precision and consistent quality.
Only a limited number of companies worldwide possess the infrastructure to stably mass-produce such high-precision components. Shibaura Electronics is one of them, and its position as one of the world’s largest market shares in the NTC thermistor field demonstrates the high regard in which the market holds the company’s technological capabilities and supply system.
Reasons Why Customers Choose Shibaura Electronics
In fields requiring advanced technologies, such as temperature sensors like thermistors, market leadership is not determined solely by company size. It stems from years of accumulated technological expertise in areas such as materials technology, manufacturing processes, and application-specific design know-how. These are not things that other companies can easily replicate in a short period.
Shibaura Electronics pioneered mass production technology for glass-encapsulated thermistors and has established a world-leading position in the NTC thermistor field. Its product lineup ranges from glass-encapsulated leaded thermistors used in environments requiring high precision, stability, and durability to automotive temperature sensors and various sensor assemblies that demand stringent safety and reliability standards.
These products are supported by unique development and manufacturing technologies that have been continuously refined for over 70 years, and have received high praise not only in Japan but also in overseas markets.
What further highlights the company’s strengths is its deep technical relationships with customers. Shibaura Electronics has established a vertically integrated system that handles everything from product development to manufacturing and quality control in-house. This system allows for direct collaboration with customers at the engineering level and enables rapid response to specification changes. It also maintains the consistency of quality that is essential in fields where high reliability is required.
In fields such as automotive, medical, and industrial equipment, changing a supplier of sensing components that has already been qualified is not simply a matter of reviewing procurement options. It requires a process of re-evaluating and re-qualifying safety and performance, which is time-consuming and costly. The trust that Shibaura Electronics has built through its long track record is a crucial element that supports strong relationships with customers in these high-barrier-to-entry markets.
Businesses That Support Challenges That Industry Absolutely Cannot Afford to Fail at
Electrification, the spread of renewable energy, and stricter safety standards represent major changes for society, and they present significant growth opportunities for the sensing industry.
Electric vehicles require more temperature monitoring than conventional cars. In smart buildings, distributed sensing throughout the building is essential to improve energy efficiency. Automated factory lines require precise environmental control to maintain stable operation.
In particular, automotive temperature sensors are one of the most critical components in modern EV power trains, directly affecting safety. Battery thermal management affects driving range, performance, lifespan, and safety.
The company states the following in its corporate materials:
“The more environmentally conscious and safety-conscious a product is, the more precise temperature control it requires. This means that the number of temperature sensors needed for that product increases.”
For new entrants, replicating in a short period the manufacturing infrastructure, proprietary technologies, and global customer base that Shibaura Electronics has built over several decades is no easy feat.
Business Scale and Stability That Support Long-Term Trust
Shibaura Electronics employs approximately 4,100 people across its global group and operates one of the world’s largest thermistor element factories. It also operates thermistor sensor assembly factories at three overseas locations and four domestic locations.
The company’s automated production system is designed to handle everything from mass-produced products to small-batch, custom-made products with consistent quality. This allows customers to reliably procure the optimal temperature sensors to suit their specific applications and requirements.
Furthermore, the company has maintained operating income for over 10 years, demonstrating stable demand in the markets in which it operates and the reliability of its business operations. Shibaura Electronics’ products are used in a wide range of fields, including automotive, HVAC, consumer electronics, housing equipment, medical technology, and industrial equipment. This diversity in business fields contributes to a certain degree of resilience to economic fluctuations.
Sustainability: Towards a More Sustainable Society Through Both Products and Business Operations
Shibaura Electronics occupies a distinctive position from a sustainability perspective. Its core products are important technologies that support the global energy transition, and the company itself is also working to reduce its environmental impact.
From a product perspective, precise temperature sensing is essential for improving energy efficiency. HVAC systems, heat pumps, and energy management systems all utilize accurate, real-time temperature data to reduce wasted energy consumption and optimize performance.
In electric vehicles, advanced battery thermal management, achieved through high-precision automotive temperature sensors, contributes not only to ensuring safety but also to improving energy efficiency and extending battery life. As global demand for EVs and energy-saving home appliances expands, Shibaura Electronics’ products become part of the hardware that makes these performance improvements possible.
In terms of business operations, the company has expressed its support for the TCFD framework and is working towards disclosing climate-related information. The Shibaura Electronics Group has set a goal of achieving carbon neutrality by 2050, and has set interim targets of reducing CO₂ emissions by 25% by 2030 and by 50% by 2040, with 2021 as the base year.
Shibaura Electronics’ approach to sustainability is rooted in its corporate mission: “To protect the global environment, contribute to the improvement of life, and promote the culture and happiness of people around the world.” This philosophy deeply intertwines with the role that the company’s products play in a global economy advancing electrification and prioritizing energy efficiency.
Prospects
The world expects the importance of precision sensing to increase even further as the energy transition accelerates and global safety standards in the automotive, medical, and industrial fields become stricter. Technologies that accurately measure and control temperature are playing an increasingly crucial role in supply chains that support next-generation industrial infrastructure.
Shibaura Electronics holds a solid position in the market, backed by deep technical relationships with customers, a vertically integrated production system, its own proprietary technology, and a steady revenue base. These strengths will further enhance the company’s presence as industrial infrastructure develops worldwide.
