Established in 1945 as a company specializing in electric wires and cables, TATSUTA Electric Wire & Cable initially manufactured power supply/distribution and telecommunication cables, widely contributing to the building of infrastructure during Japan’s high-growth period. TATSUTA also developed optical cables and supported the growth of optical networks by offering product lineups with unique features. TATSUTA then undertook the manufacture and sale of products related to electronics, and in 1984 commenced operation of its production plant for bonding wire, which has been one of its core products ever since.
As a result of diligent R&D efforts, TATSUTA has brought to the market numerous electronic materials and optical components, such as fiber optic couplers and EMI shielding film, which was launched in 2000. This product achieved significant sales worldwide with the market growth of cell phones, especially smart phones. TATSUTA operates seven business sectors, including the Sensor and Medical Business, applying the company’s unique optical technology to various fields so as to contribute to society and broaden our rich potential.
