We started our business as a company of Silk-reeling at Maruko (Ueda-City) in Nagano Prefecture in Japan at 1950. Targeting “a reliable company, a company with high quality, and a company contributing to society” have been growing up. Responding to changes in economic development, we started production of electrolytic capacitors and film capacitors, and in the turbulent electronics industry, we constantly acquire the reputation of the trusted TK brand by developing distinctive products for customer's needs. In the borderless world, we strengthen the collaboration with major electronics companies outside Japan, and started selling their electric parts such as LCD module. And we have expanded a selling business by controlling products through our quality control system which we developed as a manufacturer. We will contribute to our society by developing the product which protects the natural environment.
