PROBLEM TO BE SOLVED: To enable the arrangement of a sound insulation member having a simple and space-saving structure for reducing noise of an inclined magnetic field coil in the MRI apparatus. SOLUTION: A sound insulation cover for covering a surrounding area of the inclined magnetic field coil is constituted with different members composed of more than at least two kinds of density for some parts of the surface. Alternatively, an enclosed space storing the inclined magnetic field coil is formed in the MRI apparatus, and a vacuum tank is arranged with the sound insulation member for maintaining vacuum inside the static magnetic field generating part of the inclined magnetic field coil as a wall surface at the static magnetic field generating space of the enclosed space.
