PROBLEM TO BE SOLVED: To provide a terminal connection structure of a superconductive cable wherein power loss can be reduced.SOLUTION: The terminal connection structure J1 of a superconductive cable includes a cable core having n layers (four layers) superconductor layers 102 formed by winding multiple superconducting wires, and usual conductive terminal hardware F1 for connecting the superconductor layers 102 and usual conductive power equipment. The terminal connection structure further includes a winding portion 2 in which the number of superconductor layers is n layers (four layers) at a point immediately before a point where the superconductor layers are brought into contact with the usual conductive terminal hardware F1. It further includes a rearrangement portion 3 in which the superconducting wires are unwound and rearranged in n-1 layers (two layers) or less at the point where the superconductor layers are brought into contact with the usual conductive terminal hardware F1, the inside diameter of the innermost layer of the rearrangement portion is larger than the inside diameter of the innermost layer of the superconductor layers of the winding portion 2, and the end portions of the individual superconducting wires in the individual layers are substantially aligned at the rearrangement portion. The terminal connection structure further includes a joining portion 4 at which the superconductor layers of the rearrangement portion 3 and the usual conductive terminal hardware F1 are connected together by soldering. |
