There is provided a superconductive cable capable of absorbing an amount of contracting a superconductive wire member in cooling by a simple constitution. A superconductive cable according to the invention is a cable including a superconductive wire member constituting a superconductive layer (a conductor layer 13, a return line conductor 17) by being wound spirally, a stress relaxation layer (an inner side stress relaxation layer 12, an insulating layer/outer side stress relaxation layer 16) provided on an inner side of the superconductive layer, and a cable constituting member (a former 11) provided on an inner side of the stress relaxation layer. The cable is constituted to absorb an amount of contracting the superconductive layer in accordance with cooling the superconductive wire member by a refrigerant in a diameter direction by the stress relaxation layer. |
