ABSTRACT:
According to an aspect, a tape-type high temperature superconducting wire is provided by applying compression work to a wire manufactured by drawing so that an oxide high temperature superconductor is divided into a plurality of superconductors by a stabilizing material of substantially equal thickness. According to another aspect, a high temperature superconducting wire is provided by packing a material which becomes a superconductor portion into a metal sheath which becomes the stabilizing material and applying drawing work thereto, followed by bundling an assembly of these wire in a metal sheath and applying drawing work thereto. The thickness of the superconductor portion is approximately 10% or less than the thickness of the wire. The critical current density is hardly decreased in the high temperature superconducting wire even if subjected to bending work.
