PROBLEM TO BE SOLVED: To provide a structure for preventing the contact resistance of a fixing part of a shim coil terminal, for correcting the irregularity of static magnetic fields, from being affected by the Lorentz force acting on a gradient magnetic coil. SOLUTION: A plurality of shim coils are composed by wiring thin metal conductors 8d in a pattern formed on a film base material 8c for correcting the irregularity of static magnetic fields. The fixing parts for fixing the terminals of the plurality of shim coils are reinforced by reinforcing members 8h whose mechanical strength is stronger than that of a film of the film base material 8c. The reinforcing member 8h is made of glass fiber-including resin material, and is bonded and fixed by an adhesive material whose mechanical strength is stronger than that of the film of the film base material 8c after the adhesion hardening. Further, the area to a lead wire 8e for drawing electric signals from the terminals of the plurality of shim coils is bonded with the adhesive material, and a slit 8i is formed around the reinforcing member 8h for enhancing the mechanical strength of the contact surface between the reinforcing member 8h and the film base material 8c.
