<P>PROBLEM TO BE SOLVED: To provide a substrate for an oxide superconductive wire material capable of forming a metal stabilization layer with excellent adhesion, and to provide an oxide superconductive wire material including the substrate for an oxide superconductive wire material, an oxide superconductive wire material capable of reducing infiltration of moisture into an oxide superconductive layer, and a production method of an oxide superconductive wire material capable of producing the oxide superconductive wire material with excellent productivity. <P>SOLUTION: A substrate 1 for an oxide superconductive wire material is a metal substrate 1 for constituting a superconductive laminate 7 on one surface thereof by laminating an intermediate layer 2, an oxide superconductive layer 3 and a protective layer 4 in this order, and for constituting an oxide superconductive wire material 10 by forming a metal stabilization layer 5 around the superconductive laminate 7. The surface 1B on the reverse side of the surface 1A where the oxide superconductive layer 3 is laminated and composed of a nickel alloy has a surface roughness Ra from 50 nm to 1 μm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
