PROBLEM TO BE SOLVED: To reduce break of a tape to be wound around a sub-cable and make heat treatment before forming a coil possible. SOLUTION: A sub-cable is produced by intertwisting a plurality of supercondcutive conductors in a plurality of steps. A plurality of sub-cables 1-6 are intertwisted after tapes 11, 12 having different qualities are wound around adjacent sub-cables, and thereby, friction between tapes is reduced, and break of the tape is eliminated. |
