PROBLEM TO BE SOLVED: To provide a superconducting magnet device which includes a refrigeration unit for cooling a current lead and makes vibrations generated in the refrigeration unit unlikely to be transmitted to a superconducting coil, and to provide a current lead used in the superconducting magnet device.SOLUTION: A superconducting magnet device includes: a superconducting coil 12; a cooling container 14 housing the coil 12; a thermal insulation container 20 housing the cooling container 14; a refrigeration unit 40 disposed at a position separated from the cooling container 14; and a current lead 30 connecting the superconducting coil 12 with an external power source. The current lead 30 has a metal flexible conductor part 34. The flexible conductor part 34 extends from the cooling container 14 to the refrigeration unit 40, has a low temperature end 34a to which the superconducting coil 12 is connected and a high temperature end 34b to which the refrigeration unit 40 and the external power source are connected, and has a length dimension that deflects so as to absorb the vibrations of the refrigeration unit 40. |
