A magnetic resonance imaging apparatus includes: a magnetostatic field magnet formed in the shape of a substantially circular cylinder; a gradient coil formed in the shape of a substantially circular cylinder on the inside of the magnetostatic field magnet; a cylindrical part that is formed in the shape of a substantially circular cylinder on the inside of the gradient coil and includes at least one selected from a sound absorbing material layer and a sound blocking material layer; and a ring part that is substantially ring-shaped, covers the space formed between the magnetostatic field magnet and the cylindrical part on at least one end face of a magnet structure being formed in the shape of a substantially circular cylinder and including the magnetostatic field magnet, the gradient coil, and the cylindrical part, and includes at least one selected from an sound absorbing material layer and a sound blocking material layer.
