PROBLEM TO BE SOLVED: To enhance the opening feeling of a cylindrical hollow space to which a subject is inserted by arranging the coil wire rods of an inclined magnetic field coil asymmetrically in the static magnetic field direction, and separating the geometric center of the inclined magnetic field coil from the center of the linear area of the inclined magnetic field. SOLUTION: Coil wire rods of an inclined magnetic field coil 14 are arranged asymmetrically in the z-axial direction, and the geometric center 14c of the inclined magnetic field coil 14 is significantly separated from the center G1 of the linear area G of the inclined magnetic field. Therefore, one end part 14c of the inclined magnetic field coil 14 can be close to the uniform area S of the static magnetic field, and the opening part of a device for storing a static magnetic field magnet 12, the inclined magnetic field coil 14 and an RF coil 16 can be extended. Since the return part is present only on one side of the linear area G of the inclined magnetic field, and the inclined magnetic field coil 14 is not present within the device cover on one end part, the opening part can be extended and separated from the face of a subject 20 on a bed 22 by about 400 mm.
