A superconducting cable includes a core part, in which the core part includes a former including a plurality of copper wires, a superconducting conductor layer including a plurality of superconducting wires connected in parallel to each other, an insulating layer, and a superconducting shield layer including a plurality of superconducting wires are sequentially arranged. A conducting layer formed of a metal having a current-carrying property at room temperature is provided on opposite surfaces of each of the superconducting wires of the superconducting conductor layer to reinforce mechanical rigidity of each of superconducting wires of the superconducting conductor layer, and the former has a cross-sectional area which is smaller than that of a former of a superconducting cable in which the conducting layer is not added to superconducting wires and which is designed on an assumption that all fault current flows to the former.
