Abstract

The present invention makes full use of the advantages of a resin molded stator while pursuing advantages related to performance, reliability, and workability. Provided is an axial gap-type rotary electric machine comprising: a stator in which a plurality of core units having a magnetic flux surface in the rotational axis direction are arranged annularly around the rotational axis; a rotor facing the magnetic flux surfaces of the stator in the axial direction; a housing comprising an inner cylinder space in which the stator is accommodated; and a molded resin that covers part or all of the stator and integrally connects the stator and the inner circumference of the inner cylinder space. The housing comprises an annular thick wall section that has a predetermined thickness toward the axial center side and that follows the inner circumference in part of the inner circumference of the inner cylinder space. The axial boundary of the molded resin and the inner circumference of the inner cylinder space is included within the area of a radial projection surface of the thick wall section.
