PROBLEM TO BE SOLVED: To obtain a stator of AC power generator and a method of manufacturing the same, in which conductors do not interfere with each other at the coil ends, and the height of the coil end can be lowered. SOLUTION: A conductor of a stator coil 18 is folded toward a stator iron core 17, at the external side of a slot, in the end surface side of the stator iron core 17 and a plurality of turns, which are wound alternately forward and backward in the stator axis direction and are then folded back within the slot to alternately form an internal layer and an external layer in the slot depth direction within the slot by each prescribed number of slots, are lined in the preferential direction, while repeating the same shape in which the folding direction becomes oblique to the external circumferential surface of the stator iron core to form a coil end group 19. Here, the stator coil 18 is almost rectangular in the cross-sectional shape at least at the main portions in the slot and is almost circular or elliptical in the cross-sectional shape, at least a part including the top area of the coil end 1, resulting in the difference of cross-sectional area between the part to have almost a rectangular cross-section or a part having almost circular or elliptical cross-section.
