Patent ID: 7638463

Claim:
A method of forming an oxide superconductor thick film expressed by a general formula (Bi, Pb) 2+a Sr 2 Ca 2 Cu 3 O Z where −0.1≦a≦0.5, on a surface of a body to be processed, the method comprising the steps of: providing a mixture of a compound oxide and Pb on the surface of the body to be processed, the compound oxide having a general formula Bi 2 Sr 2 Ca 1 Cu 2 O Z ; burning the body to be processed on which the mixture is provided, to form a first thick film; and forming the oxide superconductor thick film expressed by the general formula (Bi, Pb) 2+a Sr 2 Ca 2 Cu 3 O Z where −0.1≦a≦0.5, on the first thick film.
