The Sumitomo Electric Group’s business originated in the manufacture of electric wires and cables, but since the 1950s, we have also been working to diversify our business by appropriately grasping changes in the social environment, and have introduced innovative products and technologies to the world, such as cemented carbides and sintered powder metal products, optical fibers, and compound semiconductors. Our business and range of products may look diverse at first glance, but when traced back to the roots of our technology tree, they are unique in that they are integrated into the technologies we have developed through the manufacture of wires and cables.
