    摘要： The present invention provides a method of manufacturing an oxide superconductor, including the steps of mixing oxide materials of the metals contained in an oxide superconductor represented by HgBa₂Ca₂Cu₃O 8+y to prepare a powder mixture of the composition noted above, molding the powder mixture to prepare a molded body of a desired shape, and applying a heat treatment to the molded body within a hermetic container at a temperature sufficient for bringing about a solid phase reaction of the oxide materials for at least 20 hours. Also provided is a method of manufacturing an oxide superconductor, including the steps of mixing at least one additive element selected from the group consisting of Pb, Bi, Tl, Au, Pt, Ag, Cd and In with oxide materials of the metals contained in a Hg-series 1223 type oxide superconductor to prepare a powder mixture, molding the powder mixture to prepare a molded body of a desired shape, and applying a heat treatment to the molded body within a hermetic container at a temperature sufficient for bringing about a solid phase reaction of the oxide materials for at least 10 hours.
