PURPOSE:To increase the cure rate of impregnated resin of the interface between a coil conductor unit and a main insulation and prevent a leak of said resin of said interface by arranging a curing catalyst-treated prepreg glass cloth at said interface. CONSTITUTION:A strand conductor 1 provided with a strand insulation 2 is combined with a prepreg line insulating material 3, a molding prepreg insulating material 5 and a strand insulation-reinforcing material 4 in the manner of overlapping each other to form a coil conductor unit by means of a hot forming press. Then, the surface of the coil conductor unit of this coil linear part is impregnated with a liquid prepared by dissolving Epicoat 1001 and zinc octylate in a mixed solvent of acetone and toluol and a prepreg glass cloth 6 dried to the B-stage is wound fully once around the end face of said unit in the manner of overlapping each other. After that, a main insulation 7 and a semiconductive layer 8 for suppressing an external discharge are provided thereon.
