There is provided a superconducting cable allowing a simple configuration to absorb an amount of contraction of normal conducting wire caused as it is cooled. The present superconducting cable has a superconducting layer (a superconducting conductor layer 12, a superconducting shield layer 16) and a normal conducting layer (a normal conducting conductor layer 11C, a normal conducting shield layer 17) disposed at at least one of inner and outer sides of the superconducting layer. The superconducting cable has a stress relaxation layer at an inner side of the normal conducting layer, and the superconducting cable has the stress relaxation layer 11B absorb an amount of radial contraction of the normal conducting layer caused as it is cooled by a coolant.
