Abstract: PROBLEM TO BE SOLVED: To produce 'an oxide superconductor containing Ba as a constituent element' which exhibits stably high superconductor characteristics and is free from the deterioration with the passage of time.

Based on this fact, the characteristics of the Ba-containing oxide superconductor are improved by allowing the superconductor to have such a constitution that the content of the impurity carbon is controlled to be not more than 2.0 atom.%. The Ba-containing oxide superconductor is produced by using, as the Ba-supplying raw material, BaO in which the content of the impurity carbon is reduced to be not more than 0.5% and further mixing the raw materials and synthesizing the product in a dry atmosphere in which the content of the gas containing carbon is restricted.
