A stator in which a plurality of coil conductors (3,4) of each of three phases, namely a U phase, a V phase, and a W phase, are disposed in a distributed winding form in a plurality of slots extending in an axial direction of a stator core, wherein: the coil conductors (3,4) of the three phases each include a slot conductor portion disposed in the slot, and a pair of coil end conductor portions (32,33) disposed on both axial sides (L1,L2) of the stator core to connect the slot conductor portions disposed in the different slots to each other, the stator being characterized in that each coil end conductor portion of each coil conductor (3,4) of each phase on an axial first side overlapping, in the axial direction, a coil end conductor portion of another coil conductor (3,4) of the same phase on the axial first side; and a first side transition wire portion of each of the phases, which extends in a circumferential direction in a first side coil end conductor portion serving as the coil end conductor portion positioned on an axial first side, is disposed further toward a radial inner side than an inner peripheral end surface of a tooth provided on each circumferential side of the slot so as to overlap the first side transition wire portion of another of the phases in the axial direction, wherein the first side transition wire portions of the coil conductors of two phases, from among the coil conductors of the three phases, are disposed in offset positions from each other in the axial direction, and the first side transition wire portion of the coil conductor of the remaining phase is bent in the axial direction between circumferential end portions of the coil conductors of said two phases so as to be disposed to overlap the first side transition wire portions of the coil conductors of said two phases in the axial direction. the coil conductors (3,4) of the three phases each include a slot conductor portion disposed in the slot, and a pair of coil end conductor portions (32,33) disposed on both axial sides (L1,L2) of the stator core to connect the slot conductor portions disposed in the different slots to each other, the stator being characterized in that each coil end conductor portion of each coil conductor (3,4) of each phase on an axial first side overlapping, in the axial direction, a coil end conductor portion of another coil conductor (3,4) of the same phase on the axial first side; and a first side transition wire portion of each of the phases, which extends in a circumferential direction in a first side coil end conductor portion serving as the coil end conductor portion positioned on an axial first side, is disposed further toward a radial inner side than an inner peripheral end surface of a tooth provided on each circumferential side of the slot so as to overlap the first side transition wire portion of another of the phases in the axial direction, wherein the first side transition wire portions of the coil conductors of two phases, from among the coil conductors of the three phases, are disposed in offset positions from each other in the axial direction, and the first side transition wire portion of the coil conductor of the remaining phase is bent in the axial direction between circumferential end portions of the coil conductors of said two phases so as to be disposed to overlap the first side transition wire portions of the coil conductors of said two phases in the axial direction.
