1. A superconducting magnet device comprising:
a superconducting coil;
a vacuum vessel that accommodates the superconducting coil;
a current lead that is connected to the superconducting coil and installed in the vacuum vessel;
a power supply cable that is disposed outside the vacuum vessel and connected to the current lead; and
a heating unit that is disposed outside the vacuum vessel and apart from the current lead to heat the current lead via the power supply cable,
wherein the current lead comprises a coil-side end connected to the superconducting coil and an airtight terminal mounted on the vacuum vessel opposite to the coil-side end, and
wherein the heating unit is disposed on the power supply cable apart from the airtight terminal.
