Abstract:
Provided is a gradient coil capable of suppressing generation of an unnecessary magnetic field component while ensuring the readiness of conducting wire winding work. The gradient coil includes a cylindrical bobbin round which the conducting wire is wound; and a winding part formed by winding the conducting wire round the bobbin by a plurality of turns, wherein the winding part has a first winding part in which the conducting wire is wound round the bobbin orthogonal to the axis of the bobbin in a circumferential direction of the bobbin and a second winding part in which the conducting wire is spirally wound round the bobbin, skewing relative to the axis of the bobbin in the circumferential direction of the bobbin.
