Abstract: The superconductive wire (100) includes a substrate (10), an intermediate layer (20), a superconductive layer (30), a plurality of first precipitates (40) and/or a plurality of second precipitates (42). The substrate (10) has a first main surface (10a). The intermediate layer (20) has a second main surface (20a) and a third main surface (20b) opposite to the second main surface (20a), and is disposed on the substrate (10) in such a manner that the second main surface (20a) faces the first main surface (10a). The superconductive layer (30) is disposed on the third main surface (20b). The constituent material of the superconductive layer (30) is REBa 2 Cu 3 O x (RE is a rare earth element). The plurality of first precipitates (40) and the plurality of second precipitates (42) are dispersed in the superconductive layer (30). The constituent material of each of the plurality of first precipitates (40) and the constituent material of each of the plurality of second precipitates (42) are non-superconductive material. In a cross-sectional view orthogonal to the third main surface (20b), an aspect ratio of each of the plurality of first precipitates (40) is greater than 1.

Abstract: This invention provides a substrate for a superconducting wire used for manufacturing a superconducting wire with excellent superconductivity and a method for manufacturing the same. Such substrate for a superconducting wire exhibits the crystal orientation of metals on the outermost layer, such as a c-axis orientation rate of 99% or higher, a Δω of 6 degrees or less, and a percentage of an area in which the crystal orientation is deviated by 6 degrees or more from the (001) [100] per unit area of 6% or less.
