This is a technology and research journal introducing the research and development results, technologies, and new products of Furukawa Electric Group.

On issuing

Furukawa Electric Review No.55 introduces technologies of the Furukawa Electric Group, with a focus on superconducting technologies. Expectations are high for nuclear fusion as a safe and sustainable energy source in countries around the world. It is our hope that superconducting wire materials combining our Group’s core technologies will contribute to the realization of fusion energy, considered to be the ultimate energy to solve environmental and energy problems. Each paper will hopefully convey the goal of our Group to become a company indispensable for solving social issues.
