PROBLEM TO BE SOLVED: To provide a superconducting device capable of suppressing entry of heat into the superconducting device due to a current lead.SOLUTION: In a superconducting device 10 having a housing container 1, a superconducting coil 2 which is stored in the housing container 1 and cooled to a superconducting transition temperature or lower, and a current lead which is electrically connected to the superconducting coil 2 and supplies electric power from the outside: the superconducting device 10 has a separate tank 15 spatially separated from the inside of the housing container 1; the current lead includes an inner current lead 5 which is electrically connected to the superconducting coil 2 and has a surface contact part 9 exposed to the outside of the housing container 1, in the separate tank 15, and an outer current lead 6 which is different from the inner current lead 5 and has a surface contact part 17 capable of connecting with the surface contact part 9 of the inner current lead 5 in the separate tank 15; and the inner current lead 5 and the outer current lead 6 are connected to each other by surface contact of the surface contact part 9 with the surface contact part 17. |
