Zusammenfassung:PROBLEM TO BE SOLVED: To provide a rotary electric machine that has higher efficiency, and higher torque, achieved in an inexpensive and reliable method.SOLUTION: In a radial gap rotary electric machine, a stator and a rotor faces each other with an air gap, and brackets are provided on axial end surfaces of the stator and the rotor. The stator has a stator core that includes: an annular yoke section; and a plurality of winding poles that extend radially from the annular yoke section. Concentrated windings are wound around the winding poles. Leading ends of the winding poles face the rotor through the air gap. The stator core is formed by a dust core. On two side surfaces of the stator core, respective stator-side guiding sections are provided, concentrically with a radially inner portion of the stator, so as to protrude axially. The brackets have respective bracket-side guiding sections to be fitted together with the respective stator-side guiding sections. The stator-side guiding sections and the bracket-side guiding sections are fitted together so as to ensure the air gap.
