Summary:PROBLEM TO BE SOLVED: To provide a superconducting device capable of suppressing the heat penetrating into a vacuum vessel from being conveyed to a superconducting coil when a refrigerator stops.SOLUTION: According to an embodiment, a superconducting device 1 has: a superconducting coil 10 accommodated in a vacuum vessel 5; a refrigerator 7 for cooling the superconducting coil 10 by conduction cooling; a solid state heat insulation layer 11 covering the superconducting coil 10; a coil case 12 covering the solid state heat insulation layer 11; a heat transfer member 20 for conveying cold heat from the refrigerator 7 to the coil case 12; an introduction terminal 30; and a superconducting feeder 40. When the refrigerator 7 stops, heat transfer between the coil case 12 and the superconducting coil 10 is suppressed by the solid state heat insulation layer 11, and heat transfer between the introduction terminal 30 and the superconducting coil 10 is suppressed by the superconducting feeder 40 having low coefficient of heat conductivity.
