PURPOSE:To increase the reliability of jointing and eliminate laser welding, by a method wherein an auxiliary member is embedded into the end face of a coil and the coil and the auxiliary member are caulked while a projection, produced in the base of caulking, is utilized to increase the jointing strength between the end face of the coil and an insulating member. CONSTITUTION:A groove 6 is worked on the end face of a coil strand #1 by a V-punch P1. Next, an auxiliary member 7, consisting of a conductor, is inserted into the groove 6. Then, a punch P2, having a width which is 2-4 times of the width W of the groove 6, is employed to press the end face of the coil elemental wire #1 from the upper part of the end face. In this case, the edge 8 of the groove 6 is deformed by the punch P2 and is caulked so that a projection 9, formed on the deformed groove 6', wraps the auxiliary member 7. Subsequently, insulating material 10 is loaded into the groove 6' and is cured.
