<p>A superconducting wire (10) formed by twisting a bundle of a plurality of superconducting material filaments (11 to 17) in which one material filament (11) is arranged in a central portion of the filament bundle and a plurality of other material filaments (12 to 17) arranged outside the central material filament so as to surround the central one. The filament bundle is twisted in a manner that the central material (11) filament is substitued with another one of outer material filaments (12 to 17) one by one in order periodically during a twisting process along an axial direction of the filament bundle. A super-conducting cable is formed by twisting a bundle of a plurality of superconducting material wires with each other about a core member arranged at a central portion of the bundle and each of the superconducting material wires is essentially composed of the material filaments of the characters described above, wherein substituting positions of the central material filaments and outer material filaments in the respective superconducting material wires are shifted with each other along an axial direction of the material wire bundle. <IMAGE></p> |
