PROBLEM TO BE SOLVED: To provide a gradient magnet field coil apparatus 2 that is hardly damaged even when formed to be thin.SOLUTION: A gradient magnetic field coil apparatus comprises: a main coil device 3 shaped by embedding in a first resin 3a a plurality of main coils 3z for generating a gradient magnetic field and a leakage magnetic field; and a shield coil device 4 shaped by embedding in a second resin 4a a plurality of shield coils 4z, etc. for suppressing the leakage magnetic field. The shield coil device 4 is provided with an opposing region A1 which is opposite to the main coil device 3 and fixed to the main coil device 3, and with a protruding region A2 protruding from the main coil device 3, and an insulating reinforcing material 5 is embedded in the second resin 4a in the protruding region A2. A plurality of the reinforcing materials 5 are arranged in a circumferential direction of the shield coil device 4, and the second resin 4a is filled in between reinforcing materials 5 which are adjacent to each other. The reinforcing materials 5 are arranged on the main coil device 3 side with respect to the shield coils 4z, etc. |
