摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for an oxide superconductive thin film which do not cause cracks in an oxygen introduction process in spite of a thick-walled oxide superconductive thin film as a manufacturing method for an oxide superconductive thin film which is used for manufacturing of a superconductive wire and consequently has a high Ic value, and to provide a superconductive wire having the high Ic value.
SOLUTION: In the manufacturing method for an oxide superconductive thin film which is used for the manufacturing of the superconductive wire, heat treatment is carried out while oxygen concentration is raised in the oxygen introduction process after forming an oxide superconductive thin film. The heat treatment is carried out while the oxygen concentration is controlled so as to increase a common logarithm of P at a rate of 0.5 or below per minute when the oxygen concentration is denoted by P under an environment of oxygen concentration of 1 ppm or more. Formation of the oxide superconductive thin film is performed by a coating pyrolysis method.
