A coil is configured so that: N conductor wires of wave windings each divided at at least two positions in a circumferential direction are provided in one of a plurality of slots; within a unit of the divided wave windings in which conduction is made, the N conductor wires are connected in one of series and parallel to each other at division positions located at substantially the same circumferential position of conductor-wire end portions; division units of the divided wave windings are connected in series to each other, and a total number of series turns of the series-connected division units of the each phase is a predetermined number of series turns, which does not exceed an upper limit value of a terminal voltage of the rotary electric machine; and the series-connected division units of the each phase have the same total number of series turns.
