PROBLEM TO BE SOLVED: To provide a superconducting cable for suppressing heat loss of a cooling medium to be as small as possible and achieving a compact size by not taking up a large space for installment of cooling medium piping. SOLUTION: The superconductive cable is provided with a cable core 2 with a superconductor 22, an insulating pipe 1, to which the cable core 2 is contained and an outgoing path of a cooling medium flow path is formed inside the pipe and a cooling medium recovering pipe 3 contained in the insulating pipe 1 along with the cable core 2 and forming a return path of the cooling medium flow path. The cooling medium is made to flow into a space formed between the insulating pipe 1 and the cable core 2/cooling medium recovering pipe 3, and the cable core 2 and the cooling medium recovering pipe 3 are cooled by the cooling medium. The cooling medium after cooling the cable core 2, etc., is recovered inside the cooling medium recovering pipe 3. COPYRIGHT: (C)2004,JPO&NCIPI
