- 摘要：
PROBLEM TO BE SOLVED: To provide a superconducting magnet device and a nuclear magnetic resonance imaging apparatus which can generate a static magnetic field having a high intensity while reducing a mutually attracting force between a pair of opposing static magnetic field generators in a technique for generating a static magnetic field having a high intensity.
SOLUTION: A pair of opposing magnetic field generators (30, 40) forming a superconducting magnet device (11) comprise a coolant container (35) containing a coolant (L) for cooling a main coil (31) and a shield coil (32), a fixing member (23) for concentrically fixing a first magnetizing member (21) and a second magnetizing member (22), and a linkage member (24) for linking an extension part (36) of the coolant container (35) to the fixing member (23). The first magnetizing member (21) is arranged so that the opposing inner end faces of the first magnetizing member are projected from an end face of the main coil (31) and outer end faces thereof opposed to the opposing inner end faces are recessed from the opposing end face of the main coil (31).
