A double-stator rotating electric machine includes a rotor, an outer stator having an outer multi-phase coil wound thereon, and an inner stator having an inner multi-phase coil wound thereon. Each corresponding pair of phase windings of the outer and inner multi-phase coils are formed of at least one common electric conductor wire. The electric conductor wire includes a bridging portion that bridges the corresponding pair of phase windings of the outer and inner multi-phase coils across the rotor. The bridging portion extends obliquely with respect to both radial and circumferential directions of the rotor so that radially outer and radially inner ends of the bridging portion, which are respectively connected to the corresponding pair of phase windings of the outer and inner multi-phase coils, are circumferentially offset from each other by an offset angle θ. The offset angle θ is greater than 0° and less than 180° in electrical angle.
