Summary:PROBLEM TO BE SOLVED: To provide a superconducting cable line which is applicable to a countermeasure against short circuit current and can be reduced in a diameter. SOLUTION: The superconducting cable line 1a includes a cable core 10 having a superconducting conductor layer 12 made by winding a superconducting wire rod spirally around an outer periphery of a former 11, and a heat insulating tube 5 which houses the cable core 10 and in which a space with the cable core 10 becomes a cooling medium circulating channel. A bypass conductor 21 made of a normal conductor for bypassing the short circuit current is disposed outside the cable core 10. The superconducting cable line 1a has a circulation tube 6 allowing the cooling medium in the heat insulating tube 5 to circulate outside the heat insulating tube 5, and the bypass conductor 21 is housed in the circulation tube 6.
