A superconductive cable is provided to prevent a conduction property of the superconductive cable from being degraded when the superconductive cable is contracted in cooling by arranging a cable core in a spiral shape. A superconductive cable includes a superconductive flexible cable core(1) in cryostats(2,3,4). The cable core is arranged in a wave-like shape or a spiral shape inside the cryostats. Wire networks are fixed on the cable core in specific points, which are defined in an axial direction. The wire networks are made of a material with a low thermal expansion coefficient. The wire networks are formed of an invar steel. The wire networks include at least two wires or strips, which are arranged around the cable core in a spiral shape. The wire or the strip is mechanically coupled with the cable core.
