PROBLEM TO BE SOLVED: To provide a superconductive magnetic device for which the attaching positions of refrigerant containers can be adjusted from outside of vacuum containers at the time of assembly adjustment, and to provide a magnetic resonance imaging device using the superconductive magnetic device. SOLUTION: This superconductive magnetic device is equipped with a pair of the vacuum containers 11 and 15 which are arranged to face each other across a specified space 9, the refrigerant containers 12 and 16 which are arranged in the vacuum containers 11 and 15, and main magnets 14 and 18 which are housed in the refrigerant containers together with a refrigerant, and generate a uniform static magnetic field spatial region 10 in a space 9. The superconductive magnetic device is also equipped with thermal shields 13 and 17 which enclose the refrigerant containers 12 and 16, and prevent heat from outside from entering, and a connection supporting section 3 which connects and supports both of the vacuum containers 11 and 15. Then, a position adjusting means which can adjust the supporting dimension from outside of the vacuum containers 11 and 15 under a vacuumized state is provided on a supporting member 34 which supports the refrigerant containers 12 and 16 to the vacuum containers 11 and 15.
