A stator includes a stator core having a plurality of slots arranged in a circumferential direction and a stator coil formed by wave-winding continuous coil wires on the stator core. Each of the continuous coil wires has in-slot portions received in the slots and turn portions each of which connects, on the outside of the slots, one pair of the in-slot portions. Each of the continuous coil wires has, at root parts of the turn portions respectively connected with ends of the in-slot portions, first crank portions that are radially bent. An amount of radial bending of the first crank portions is set to be half of a radial width of the in-slot portions.
