A stator includes a stator core and a stator winding. The stator core has a cylindrical shape and a plurality of slots. The stator winding includes a plurality of phase windings each including a plurality of segment conductors inserted into the slots and coupled to each other in series. Each of the segment conductors has a pair of straight parts and a bend. The pair of straight parts is accommodated in two of the plurality of slots. The bend protrudes from an end face of the stator core and couples the pair of straight parts to each other. In each of the plurality of slots, the number of the bends protruding from the end face of the stator core to extend in one of circumferential directions matches the number of the bends protruding from the end face of the stator core to extend in the other of the circumferential directions.
