To provide a superconductive cable capable of reducing loss of an alternating current.

The superconductive cable is provided with a cable core which has a superconductive conductor layer formed by spirally winding a plurality of superconductive wire rods 120 on the outer circumference of a former 11, and the superconductor layer has a multi-layer structure in which the superconductive wire rod 120 is laminated in radial direction of the cable core. Then, in the superconductive conductor layer, an outer circumference side layer is formed by winding spirally the superconductive wire rod 120 similarly on the outer circumference of the inner circumference side layer 12a, and a magnetic field smoothing layer 12m consisting of a magnetic material is installed between the inner circumference side layer and the outer circumference side layer.
