Abstract
A rotary electric machine according to the present invention includes: a stator including: a stator core; and a stator winding that is mounted to the stator core, and into which a varnish is impregnated, the stator being held by a housing in a state in which housing interfitting surfaces on two axial end surfaces of a core back portion are clamped by the housing from two axial ends, wherein a varnish leakage stopping portion is formed radially inside the housing interfitting surfaces on two axial end surfaces of the stator core so as to interrupt flow pathways of the varnish from a radially inner side onto the housing interfitting surfaces.
