SUPERCONDUCTING COIL

PROBLEM TO BE SOLVED: To provide a superconducting coil which has a winding structure exhibiting high mechanical and thermal reliability capable of preventing damage, burning, deterioration, or the like, of a superconductor when an excessive current flows, and can be manufactured inexpensively.SOLUTION: The superconducting coil includes a winding formed by winding a superconductor, consisting of a thin film superconducting wire rod produced by laminating an intermediate layer, a superconducting layer, and a stabilization metal layer on one side of a metal substrate, on the peripheral surface of a cylindrical reel. The superconductor is wound together with a stabilization material consisting of a metal tape, and the stabilization material is placed at least on the inner diameter side of the superconductor. The superconductor is wound so that the stabilization metal layer surface and the metal substrate surface are the inner diameter side and the outer diameter side, respectively.
