Zusammenfassung:Provided is a rotating electrical machine having improved cooling performance. The rotating electrical machine is provided with a stator (12) having a stator core (24) and a stator coil (26), 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 forming section (40) provided on the outer periphery of the stator core has a first flow path (F1) extending from one end to the other end in the axial direction of the stator core, and a second flow path (F2) provided on the outside in the radial direction of the first flow path and extending from one end to the other end in the axial direction of the stator core. The first bracket is provided with: an annular peripheral wall (16a) having an open end facing the one end surface of the stator core; a bottom wall (16b) facing the one end surface of the stator core with a gap therebetween; and a second flow path forming section (48) comprising a part o
