A rotary electric machine comprising: a housing; a rotor that is fixed to a shaft that is rotatably supported by said housing such that said rotor is disposed inside said housing; a stator that includes: an annular stator core in which slots are arranged circumferentially; and a stator winding that is mounted to said stator core, said stator being held on an outer circumferential side of said rotor by said housing such that an air gap (g) is interposed between said stator and said rotor; and a cooling mechanism (33, 34, 35, 36, 62) that supplies a liquid coolant to a coil end (20f, 20r) of said stator winding to cool said stator winding, characterized in that: said stator winding includes a plurality of winding bodies that are each produced by winding a jointless continuous conductor wire that is coated with insulation, and that are arranged at a pitch of one slot in a circumferential direction so as to be mounted into a first slot, a second slot, and a third slot that line up at an angular spacing of n slots in a circumferential direction, where n is a natural number that is greater than or equal to two; said winding bodies are produced by repeatedly winding a δ-shaped coil pattern that is formed by inserting said conductor wire sequentially into said second slot, said first slot, said second slot, and said third slot, so as to alternate an axial direction of insertion into said first slot, said second slot, and said third slot, for m turns in a radial direction, where m is a natural number that is greater than or equal to one, and are configured such that a plurality of rectilinear portions (22a-22d) that are respectively inserted into said first slot, said second slot, and said third slot are linked continuously by coil end portions (22e-22g); said coil end (20f, 20r) is constituted by said coil end portions (22e-22g); and said liquid coolant that is supplied to said coil end (20f, 20r) flows through a gap between circumferentially adjacent coil end portions (22e-22g) among said coil end portions. a housing;
