PROBLEM TO BE SOLVED: To provide a superconducting cable prevented from temperature increase due to heat generated at a connection part when jointing cable cores. SOLUTION: The superconducting cable, composed of cable cores 10 each having a superconducting layer 12 inserted into an inner space of an outer case, turning the inner space into a coolant layer by flowing a coolant, is made to have a conduction structure by jointing the superconducting layers 12 of the cable cores to each other. A joint insulation layer is arranged at an outer periphery of a conductor jointing sleeve (conductor jointing part) 19 jointing and externally fitting on the superconducting layers 12 of the cable cores 10 to each other. Further, a coolant flow path S communicating the coolant layer and the conductor jointing sleeve 19 is formed at the inside of the joint insulation layer 20, and the heat generated at the conductor jointing sleeve is transferred to the coolant layer through the coolant flow path S.
