A stator includes a stator core and a stator coil comprised of a plurality of electric wires. Each of the electric wires has, at least, first, second, and third in-slot portions and first and second turn portions. The first to third in-slot portions are respectively received in three different slots of the stator core. The first turn portion is located on one axial side of the stator core outside of the slots to connect the first and second in-slot portions. The second turn portion is located on the other axial side of the stator core outside of the slots to connect the second and third in-slot portions. For each of the electric wires, the radial distances of the first to third in-slot portions from the axis of the stator core successively decrease. All of the electric wires are offset from one another in the circumferential direction of the stator core.
