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 realizationof 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.
