Zusammenfassung:	An extended end portion (20) of a coil conducting wire (16) and an extended end portion (30) of a flat plate bus bar (35) are placed in parallel and adjacent to each other. The width of the bus bar (36) is wider than that of the coil conducting wire (16). On an end portion of the bus bar extended end portion (30), a tapered portion (44) is formed. Tip ends of the coil conducting wire extended end portion (20) and of the bus bar extended end portion (30) are welded to each other. As the tip end of the bus bar extended end portion is thin, welding heat is transmitted to a deeper position in the longitudinal direction of the bus bar, which results in a wider welding area. In addition, welded material flows along the slant surface of the tapered portion (44), which also results in a wider welding area.
