Abstract
Annular portions are arranged on mutually confronting surfaces at circumferential edge portions of low-temperature containers, the annular portions forming annular containing portions whose cross section is rectangular. Not only a side coil among a group of coils forming a collective coil body is disposed inside the containing portion, but also a gradient magnetic field unit, a radio-frequency transmission coil, and a reception coil are disposed inside a recessed portion so as to be integrated with one another into a single body, the recessed portion being formed so as to be surrounded by the corresponding annular portion. The side coil supplies more than half a designed magnetomotive force. Since a distance J of the mutually confronting low-temperature containers, i.e., the distance between the mutually confronting surfaces of the side coils can be reduced by a distance corresponding to the projection of the projected portions, not only the designed magnetomotive force can be reduced, but also the apparatus can be downsized and inexpensive.
