Our Businesses and the Trajectory of Our Growth

The Sumitomo Electric Group was founded as a manufacturer of electric wires and cables, but in the 1950s, we decided to diversify our business to accurately grasp changes in the world and respond to them. Since then, we have used our technology for manufacturing electric wires and cables as a base to develop revolutionary new products and technologies, such as cemented carbide tools, sintered powder metal products, optical fibers and compound semiconductors. We now have five major global business segments: Automotive, Electronics, Environment & Energy, Infocommunications and Industrial Materials.
