It will soon be 100 years since the phenomenon of "superconductivity" was first discovered. Attempts to put superconductivity to practical use began in the 1960s, and the competition in development of superconductivity materials has been fought around the world since then. Fujikura joined in the development of superconducting wires in the late 1980s. Since then, Fujikura has produced a succession of epochal results and contributed to the technological evolution of superconductivity, although the company started late. The following pages reflect the progress of the attempts and creation by Fujikura, which has made an imprint on the history of the superconductivity revolution with many miraculous breakthroughs.
