Abstract

A superconducting wire comprises a wire element wherein a plurality of superconducting filaments are arranged in a metallic matrix, and a covering layer which is formed on the surface of the wire element with a number of filaments and has a laminated structure including at least one insulator film as the lower layer and at least one thermal conductor film as the upper layer. Frictional heat generated on the surface of the superconducting wire is prevented from being conducted to superconducting filaments by virtue of the presence of the insulator film, and is conducted through the thermal conductor film to be dissipated. Therefore, the temperature of the superconducting filaments is hardly raised.
