PURPOSE:To make the cable excellent in stabilization of superconductive characteristics, to make it small in AC coupling loss at AC current application, and to enable miniaturization and lightening by compounding stabilizing material made of pure copper in a superconductive cable, and making metallic ground where superconductive fibers are dispersed and arranged contain magnetic elements. CONSTITUTION:A diffusion preventive layer 11 is arranged around stabilizing material 10 made of copper so as to form a compound substance 12, and a plurality of insitu-rods which contain magnetic elements in metallic ground wherein dendrites of at least one element among plural elements which constitute a superconductive intermetallic compound are dispersed are arranged outside this compound substance 12. Further, those are covered with a metallic pipe 14, and then the diameter is reduced so as to make an element wire 15, and a plated layer 16 which contains residual elements among plural elements which constitute the superconductive intermetallic compound is formed around this element wire 15 so as to form a plated element wire 17. Next, diffusion heat treatment is applied to this plated element wire 17, whereby the elements of the plated layer 16 are diffused into the element wire so as to generated superconductive fibers. Hereby, a superconductive cable which is excellent in stability of superconductive characteristics and is miniaturized and lightened as well can be obtained.
