PURPOSE:To increase the connection strength between an enameled wire, a winding of a stator, and a lead wire for conduction. CONSTITUTION:At the end of an enameled wire 1, enamel is peeled off and thereby a conductor 2 is exposed. The enameled wire 1 is wound round a coated part of a lead wire 3 several times and a conductor 4 of the lead wire 3 is wound spirally round the exposed conductor 2. At the end 14 of the conductor- wound part, the edges of the conductors 2 and 4 are trued up and the end 14 is inert gas shielded tungsten arc-welded or plasma-welded or welded by the other methods to connect the conductors 2 and 4. The conductor 2 is exposed, because the end of the enameled wire 1 is high-frequency heated and thereby enamel is peeled off and softened and finally removed.
