1. A stator for a rotary electric machine, the stator comprising:
a stator core having a hollow cylindrical shape, the stator core comprising a core inner-peripheral portion including slots; and
a stator winding comprising a phase winding, the phase winding comprising segment conductors held in the slots, wherein
the phase winding comprises parallel conductors connected to one another in series,
each of the parallel conductors comprises ones of the segment conductors connected to one another in parallel,
the segment conductors comprise weld end portions that protrude from the slots, that are bent in circumferential directions of the stator core, and that constitute conductor joint portions each of which includes one of the weld end portions welded to another of the weld end portions,
weld end portions which protrude from one of the slots among the weld end portions comprise:
first weld end portions bent in one of the circumferential directions of the stator core; and
second weld end portions bent in another of the circumferential directions of the stator core, a number of the second weld end portions being less than a number of the first weld end portions,
ones of the conductor joint portions are configured with the first weld end portions, the ones of the conductor joint portions comprising an outer conductor joint portion located on an outer side of the stator core in a radial direction of the stator core, the outer conductor joint portion being at least partly located on an outer side of the core inner-peripheral portion in the radial direction, and
a value obtained by dividing a number of segment conductors held in one of the slots among the segment conductors by a number of segment conductors that constitute one of the parallel conductors among the segment conductors is an odd number.
