PROBLEM TO BE SOLVED: To solve the problem that a void can be caused in a gradient magnetic field coil apparatus for an MRI produced by resin impregnation. SOLUTION: Between a Z-axis gradient magnetic field coil 11 and an X-axis gradient magnetic field coil 12, and between the X-axis gradient magnetic field coil 12 and a Y-axis gradient magnetic field coil 13, two or more tape-state insulators 51 are arranged with intervals therebetween in parallel with the surface of the coils. Resin injected by a die not shown in the figure flows with intervals between the tape-state insulators 51 as channels 71 for impregnation and the resin is hardened. Thus, the gradient magnetic field coil apparatus which has no void and which has satisfactory insulation is produced. COPYRIGHT: (C)2008,JPO&INPIT
