In the magnetic resonance imaging device, the distance between the first and second coils is different in the circumferential direction and has a first region (A1) (&thetas;=0, &pgr;) and a second region (A2) (&thetas;=&pgr;/2) narrower than the first region (A1). In the first coil, wiring patterns (17a, 17b) on the side of a zero-plane (F0) passing through the center of the first coil and perpendicular to the axis direction (z-axis direction) meander in the circumferential direction such that the wiring patterns (17a, 17b) depart from the zero-plane (F0) in the first region (A1) and approach the zero-plane (F0) in the second region (A2). This provides a gradient magnetic field coil capable of configuring wiring patterns without using a loop coil that does not pass through the z-axis. |
