PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging device having an inclined magnetic field coil with reduced vibration, noise and temperature rise. SOLUTION: Cooling vessels 2 for housing a superconducting coil inside are oppositely arranged in the vertical direction by sandwiching a uniform magnetic field area, and an inclined magnetic field coil assembly 14 composed of a main coil 5 and a shield coil 6 of an inclined magnetic field coil and an intermediate member 13B of a rigid body inserted between both coils is fixed to these cooling vessels 2 by a fixing tool 22. Here, the intermediate member 13B is formed in a disk shape, a refrigerant inlet 30 and a refrigerant outlet 31 are installed on a side surface, and a refrigerant passage is formed inside. A circulating means of a refrigerant is arranged outside a device, and this is connected to the refrigerant inlet 30 and the refrigerant outlet 31 by a conduit to flow the refrigerant to the refrigerant passage to cool the main coil 5 and the shield coil 6 joined to the intermediate member 13B.
