A stator includes a hollow cylindrical stator core and a stator coil made up of wave-shaped electric wires. Each of the electric wires has in-slot portions, which are received in slots of the stator core, and turn portions that are located outside of the slots to connect the in-slot portions. The stator coil includes first crank-shaped portions and second crank-shaped portions. Each of the first and second crank-shaped portions is provided, in one of the electric wires, at the center of an apex part of one of the turn portions and is radially bent to shift the radial position of the electric wire. The amount of radial position shift made by each of the second crank-shaped portions is less than that made by each of the first crank-shaped portions. The second crank-shaped portions are located at a plurality of places in the circumferential direction of the stator core.
