Summary:PROBLEM TO BE SOLVED: To achieve stable electrification by reducing the peeling stress acting on a thin film superconductive wire thereby preventing the superconducting characteristics of a superconducting coil from degrading, while ensuring insulation performance of the axial end face of the superconducting coil.SOLUTION: A superconducting coil 10 includes a winding 14 formed by winding a superconducting tape wire 11 of tape shape having multilayer structure around a spool 13 together with an insulation tape wire 12, and an insulation layer 15 bonded to an axial end face of the winding 14. The ratio W2/W1 is set to satisfy a relation W2/W1≤1.15, where W1 is the width of the superconducting tape wire 11, and W2 is the axial depth of the winding 14 including the insulation layer 15.
