A magnetic resonance imaging apparatus according to an embodiment includes a static magnetic field magnet, a gradient coil, a bore tube and a sealed space forming unit. The gradient coil is formed to be approximately cylindrical, arranged in a cylinder of the static magnetic field magnet, and adds a gradient magnetic field to the static magnetic field. The bore tube is formed to be approximately cylindrical and arranged in the cylinder of the gradient coil. The sealed space forming unit forms a sealed space enclosing the gradient coil between an inner circumferential side of the static magnetic field magnet and an outer circumferential side of the bore tube. At least a part of at least one of the side ends of the gradient coil does not make contact with the sealed space.
