Zusammenfassung:According to one embodiment, an electric rotary machine includes a stator (12) including a stator core (24) and a stator coil, a first bracket (16) covering one end surface of the stator core, a second bracket (18) covering the other end surface of the stator core, and a rotor (28). A first flow path formation part (40) provided on an outer periphery of the stator core includes a first flow path (F1) extending from one end of the stator core to the other end thereof in the axial direction and a second flow path (F2) extending from one end of the stator core to the other end thereof in the axial direction. A first bracket includes an annular peripheral wall (16a) with an opening end opposed to the one end surface, a bottom wall (16b) opposed to the one end surface with a gap therebetween, and a second flow path formation part (48) formed as a part of the peripheral wall. The second flow path formation part defines an external air flow path (RA) and an internal air flow path (RI).
