<P>PROBLEM TO BE SOLVED: To provide an oxide superconductive wire material in which, even though a lamination is thick, Jc is not reduced and an oxide superconducting layer having a sufficiently high Ic proportional to the thickness the lamination is formed on a substrate plate, and provide a manufacturing method of the oxide superconductive wire material. <P>SOLUTION: A manufacturing method for an oxide superconductive wire material in which organic metallic compound is used as raw material and an oxide superconducting layer is formed by a coating pyrolysis method on an orientation metal substrate, includes a coating film forming process for forming a coating film of the organic metallic compound, a temporary baking treatment process for forming a temporary baked film by pyrolyzing and removing organic components contained in the coating film, and a formal baking treatment process for forming a formal baked film by crystallizing the temporary baked film. The coating film forming process, the temporary baking treatment process, and the formal baking treatment process are repeated so as to form and stack a plurality of formal baked films, so that the oxide superconducting layer in which a defective layer is formed between the stacked films is formed. An oxide superconductive wire material has a plurality of formal baked films which are stacked via a defective layer by the coating pyrolysis method. <P>COPYRIGHT: (C)2012,JPO&INPIT |
