A rotary electric machine comprises a two-pole rotor, a three-phase armature winding, and a stator core having fifty-four slots. An armature winding is stored as a top coil piece and a bottom coil piece in two layers in the slot of the stator core and has three parallel circuits and two phase belts per one phase. Each phase belt includes two parallel circuits. When a sequence of the first and second parallel circuits of one phase belt is viewed from a side closer to a phase belt center, those parallel circuits are arranged in a sequence of the first, second, first, first, second, first, first, first, and second parallel circuits in the top coil pieces and in a sequence of the first, second, first, first, second, first, first, first, and second parallel circuits in the bottom coil pieces to be connected to the top coil pieces. For a sequence of the second and third parallel circuits of the other the phase belt, those parallel circuits are arranged in a sequence of the third, second, third, third, second, third, third, third, and second parallel circuits in the top coil pieces and in a sequence of the third, second, third, third, second, third, third, third, and second parallel circuits in the bottom coil pieces to be connected to the top coil pieces.
