Summary:PROBLEM TO BE SOLVED: To further improve critical current characteristics in a magnetic field while reducing a raw material cost.SOLUTION: A heating step of heating a long base material 11, a deposition step of depositing an oxide superconductor on the base material 11 in a heated state using a CVD method, and a cooling step of cooling the base material 11 are sequentially repeated so that heat capacity per layer is 0.4-2.0 J/h inclusive, to form a superconducting layer 13 of a multilayer film.
