摘要：
An axial air-gap rotary electric machine includes a stator, a coil, and a bobbin. The bobbin includes a tube and a flange. The coil is wound on the outer periphery of the tube portion with regular winding. A number of turns of each of a plurality of layers wound around an external side of a last layer in contact with the flange is at least one less than a number of turns of each of a plurality of layers wound around an adjacent internal side of the last layer.
