Abstract
A stator for an electric rotating machine is equipped with a stator winding made up of a plurality of conductor segments. Each of the conductor segments has a head and two legs. The legs are inserted through their respective slots formed in a stator core, so that each of the conductor segments has leg ends protruding from either one of opposed end surfaces of the stator core and the head thereof protruding from the other end surface. Radially adjacent two of the leg ends are provided as a coil end pair to be welded. At least one of the heads is interposed between adjacent two of the coil end pairs, thereby ensuring a distance between the two adjacent coil end pairs which is great enough to provide a required degree of electric insulation between the coil end pairs when the leg ends of the conductor segments are welded electrically.
