PROBLEM TO BE SOLVED: To enhance the performance and the reliability in a superconductive magnet provided with a cold storage refrigerator having a magnetic cold storage material. SOLUTION: A superconductive magnet is provide with a superconductive coil, a vacuum tub fixed with the superconductive coil, so as to enclose the superconductive coil, a magnetic shield enclosing the vacuum tub, and an adjusting mechanism capable of adjusting the relative position between the magnetic shield and the superconductive coil by adjusting the relative position between the magnetic shield and the vacuum tab. In addition, the superconductive magnet is provided with the superconductive coil, a radiation shield enclosing the superconductive coil, the vacuum tub fixed with the superconductive coil through the radiation shield and enclosing the radiation shield, the magnetic shield enclosing the vacuum tub, and the adjusting mechanism capable of adjusting the relative position between the magnetic shield and the superconductive coil by adjusting the relative position between the magnetic shield and the vacuum tub.
