In a method of manufacturing an oxide superconducting wire including steps of performing heat treatment and deformation processing in a state of filling up a metal sheath with powder of an oxide superconductor or raw material therefor, fine particles or gas adsorbed by the powder can be desorbed by heating the powder at least once preferably under decompression in a stage before final sintering of the powder. It is possible to further withdraw the adsorbed fine particles or gas by heating the powder under decompression at least once before the same is covered with the sheath, covering the powder with the sheath, deforming the sheath and again heating the same under decompression, for example. Thus, it is possible to prevent gas generation from the powder during heat treatment for further growing superconductive particles, thereby preventing the superconducting wire from inflation etc. caused by such gas generation. <IMAGE> |
