The present invention provides an AC generator for use in a vehicle, which eliminates the need for metallic terminals, and which reduces the number of components and the number of man-hours needed for a connecting operation to thereby reduce the cost thereof and enhance the reliability thereof. Each of conductor wires of a stator winding has a circular cross section and also has an end portion at which a connection latch portion to be connected to a mounting seat of a rectifier is formed. The connection latch portion is constituted by deforming an end portion of each of the conductor wires like a plate and subsequently forming a cutout in the end portion deformed like a plate.
