Abstract: In a superconducting coil used in an MRI apparatus, it is necessary to arrange a superconducting wire at a desired position to obtain a desired coil shape in order to obtain a temporally stable static electromagnetic field with high strength and high uniformity. A superconducting coil includes a winding frame, a spacer disposed on an outer periphery of winding frame and including a winding groove having a spiral shape and a communication groove provided between winding grooves, and includes a coil group having a superconducting wire wound in winding groove. It is therefore possible to obtain superconducting coil having a desired coil shape.
