A rotary electric machine includes a stator including a plurality of teeth which are each wound up by a coil and a stator yoke core connecting the respective teeth, and a rotor provided with magnets disposed so as to oppose to the teeth, respectively, with a space therebetween. Each of the teeth has a surface opposing to the magnet of the rotor, and the opposing surface is formed with a protruded portion at substantially central portion thereof in the circumferential direction of the stator.
