PROBLEM TO BE SOLVED: To obtain an AC generator, capable of improving productivity of a stator and preventing short circuit accidents, in a coil end group by constituting stator windings of respective phases of a plurality of windings constituted by winding long-sized strands. SOLUTION: Polyphase stator windings 16 are constituted by connecting first to fourth windings 31 to 34 in series. First to fourth windings 31 to 34 are constituted by winding in wave form the respective one strands 30, so as to alternately adopt inner layers and outer layers in the slit depth direction in a slit 15a at each six slits. The turns of the strands 30 folded back at the end face sides of the core 15 are aligned in the circumferential direction to constitute the coil end group.
