<P>PROBLEM TO BE SOLVED: To provide a high temperature superconductive wire material where insulating coating is performed on an entire outer periphery, and to provide a high temperature superconductive coil using the high temperature superconductive wire material. <P>SOLUTION: A high temperature superconductive wire material 10 of this invention includes: a superconductive laminated body 5 formed by laminating a substrate 11, an intermediate layer 12, an oxide superconductive layer 13, and a metal stabilization layer 4 in this order; and an insulation coating layer 7 coating an outer peripheral surface of the superconductive laminated body 5 and formed by baking a resin. Corner parts 5a in a cross section along the width direction of the superconductive laminated body 5 are formed into curved surfaces having curvature radii. The thickness of the insulation coating layer 7 is 12 μm or more, and the curvature radius of each corner part 5a is 14.5 mm or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
