Abstract
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 (A) (θ=0, π) and a second region (A) (θ=π/2) narrower than the first region (A). In the first coil, wiring patterns () on the side of a zero-plane (F) 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 () depart from the zero-plane (F) in the first region (A) and approach the zero-plane (F) in the second region (A). 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.
