PURPOSE: To obtain a producing method of superconductor capable of giving toughness to a superconductor and producing the superconductor connectable to an electrode with low contact resistance at the time of producing a 123 based oxide superconductor. CONSTITUTION: In the producing method of the 123 based oxide superconductor by using a 123 composition raw material to be superconducting phase and a 211 composition raw material to be insulating phase as raw material compositions and applying a partial-fusing unidirectional-solidifying process, 5-50 pts.wt. silver or argentous oxide powder per 100 pts.wt. total quantity of the 123 composition raw material and the 211 composition raw material is added to the raw material composition. |
