<P>PROBLEM TO BE SOLVED: To provide a superconductive cable excellent is superconductive characteristics by reducing mechanical degradation of a superconductive wire rod. Ž<P>SOLUTION: The superconductive cable 1 is configured such that three cable cores 2 provided with superconductive layers 4 are stranded and housed in a heat shielding tube 6. The superconductive layers 4 (a superconductive layer 4c, a superconductive shield layer 4s) are configured by winding spirally a metal matrix superconductive wire rod 40 containing a plurality of spirally stranded superconductive filaments embedded in a metal matrix. A direction of stranding of the superconductive filaments in the superconductive wire rod 40 and a direction of winding of the wire rod 40 are different. In the superconductive cable 1, since a stranding of the same direction as the direction of winding of the superconductive wire rod 40 is not added to the superconductive filaments, mechanical degradation of the superconductive filaments due to the above stranding can be suppressed.
