A rotating electrical machine includes an annular stator, a motor case, and an inner frame. The motor case is disposed radially outward of the stator with a prescribed radial gap. The inner frame fixedly supports one end of the stator in the axial direction of the motor case. The inner frame includes a bolt fastening portion coupled to the one end of the stator without being coupled to the motor case, a bolt fastening portion coupled to the motor case without being coupled to the one end of the stator, and a connecting portion connecting the bolt fastening section and the bolt fastening section. The radial rigidity at the connection section of the inner frame is configured to be lower than the radial rigidity of a bottom section of the motor case.
