A rotary electric machine includes an armature winding having three parallel circuits and two phase belts per phase. Each phase belt includes two parallel circuits, which are arranged in a sequence of the first, second, first, first, second, first, first, first, and second parallel circuits in top coil pieces and in a sequence of the first, second, first, first, second, first, first, first, and second parallel circuits in bottom coil pieces to be connected to the top coil pieces. A sequence of the second and third parallel circuits of the other the phase belt are arranged in the third, second, third, third, second, third, third, third, and second parallel circuits in the top coil pieces and in 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.
