Abstract
A high-temperature superconducting coil according to the invention includes an oxide superconducting wire including a tape-shaped substrate, an intermediate layer being stacked on the substrate, an oxide superconducting layer being stacked on the intermediate layer, and a metal stabilized layer being stacked on the oxide superconducting layer; a coil main body being formed by winding the oxide superconducting wire in a coil shape; and an impregnated resin layer being formed of an impregnated resin of which a thermal shrinkage rate indicating a rate of change of a length when cooling is performed from 293 K to 140 K is greater than or equal to −0.517%, the impregnated resin layer covering the coil main body.
