PROBLEM TO BE SOLVED: To provide a production method of a tape-like oxide superconductive wire rod which is suppressed in peeling off of a protective layer from a superconductive layer in every part of the superconductive layer throughout the longitudinal direction, even when the superconductive wire rod is long-sized, and has stable quality.SOLUTION: A production method of a tape-like oxide superconductive wire rod comprises applying a raw material solution containing a metal element constituting a REBaCuO-based superconductive layer 13 (RE is one or more elements selected from Y, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm and Yb; y≤2; and z=6.2-7) on an interlayer 12 formed on a tape-like substrate 11 and conducting a baking heat treatment. The raw material solution contains a silver complex, and the silver complex is a silver organic acid salt using the same organic acid as that of one of organic acid salts of RE, Ba and Cu, elements in the raw material solution. On the superconductive layer 13, a silver layer is formed tightly as a protective layer 14. |
