PROBLEM TO BE SOLVED: To provide a superconducting magnet unit ensuring stabilized conduction by preventing the critical current level from lowering without lowering the allowable current density at a current supply section even in case of a refrigerator cooling type where thermal load is heavy due to heat generation and the exciting current is high, for example. SOLUTION: Independently from a first cooling means 6 for cooling a superconducting coil 1 down to the operating condition, a second cooling means 10 for removing heat generated from a section 8 for supplying a current to the superconducting coil 1 is provided.
