Claim:
1. A rotating electric machine comprising: a rotor; a stator including an annular stator core and a three-phase stator coil, the stator core being disposed in radial opposition to the rotor and having a plurality of slots arranged in a circumferential direction of the stator core, the stator coil being comprised of a plurality of phase windings star-connected to one another, the phase windings being partially received in the slots of the stator core so that parts of the phase windings are located outside the slots to make up a pair of coil ends of the stator coil, the coil ends protruding respectively from an opposite pair of axial end faces of the stator core, wherein each of the phase windings of the stator coil is comprised of a plurality of winding segments, the stator coil further has a plurality of intraphase bridging wires electrically connecting the winding segments of the same phase and a plurality of interphase bridging wires electrically connecting neutral point-side ends of the phase windings, and all of the intraphase and interphase bridging wires are arranged on one of the coil ends of the stator coil so that at least one of the intraphase bridging wires is in direst contact with at least one of the interphase bridging wires, wherein at least one of the intraphase bridging wires electrically connects a pair of ends of the winding segments of the same phase to each other, one of the pair of ends being led out from a radially outer periphery of the coil end of the stator coil and the other end being led out from a radially inner periphery of the coil end.
