A magnetic resonance imaging apparatus according to an embodiment includes a static magnetic field magnet, a gradient coil, a space forming structure, a magnet supporting member, and a space forming structure supporter. The gradient coil is provided on an inner circumferential side of the static magnetic field magnet. The space forming structure forms a patient space on an inner circumferential side of the gradient coil. The magnet supporting member supports the static magnetic field magnet on a floor surface. The space forming structure supporter is attached to the magnet supporting member and supports the space forming structure.
