PROBLEM TO BE SOLVED: To improve reliability in the interlayer insulation and insulation to the ground of an electromagnetic coil that is composed of a strand conductor to energize an AC and is used under environment exposed by radiation, and to provide a method for reducing the manufacturing cost. SOLUTION: As a coil former used when a conductor is wound for forming winding, the member of a mold die used for resin impregnation is used, as it is, and the need for dismantling the coil former or the like is eliminated, after the wiring is formed. Additionally, the mold die is used as it is, as the case of an electromagnetic coil. As a result, outflow of resin after impregnation need not be considered, thus interposing a sufficient amount of resin between the conductors by using the resin having low viscosity, hence improving interlayer insulation and insulation to the ground.
