A superconducting cable capable of absorbing contraction of a superconducting wire through a simple arrangement at the time of cooling. The superconducting cable comprises a superconducting wire wound spirally to constitute a superconducting layer (conductor layer (13), return conductor (17)), a stress relaxation layer (inner stress relaxation layer (12), insulating layer/outer stress relaxation layer (16)) provided on the inside of the superconducting layer, and a cable composing member (former (11)) provided on the inside of the stress relaxation layer. The stress relaxation layer is arranged to absorb contraction of the superconducting layer in the radial direction incident to cooling of the superconducting wire by coolant. |
