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, a superconducting shield layer) and a normal conducting layer (a normal conducting conductor layer, a normal conducting shield layer) 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 absorb an amount of radial contraction of the normal conducting layer caused as it is cooled by a coolant.
