PROBLEM TO BE SOLVED: To easily process a wire material by carrying out a first process to produce a member by filling the inside of a metal sheath with raw materials and a second process to produce an oxide superconductor. SOLUTION: As raw materials to be used in a first process, for example, La, Y, Sc, M, Cu single elements or oxides are used and these elements or oxides are mixed in stoichiometric ratios to give a raw material 2 and the inside of a sheath member 3 is filled with the raw material 2. As the member 3, materials having low electric resistance and high thermal conductivity, for example, copper, silver, gold, and alloys containing mainly these metals may be used. Then, in a second process, the member treated by a desiring processing through the first process is heated in an oxygen-containing atmosphere and the raw material 2 packed in the inside of the member 3 is converted into a continuous compound superconductive wire 1. Consequently, a compound type superconductive wire using lamella perovskite type oxide superconductor having high critical temperature can be stably produced. |
