In order to provide a rotating electrical machine capable of suppressing noise, the rotating electrical machine comprises: an annular stator (2); a motor case (4) disposed radially outward the stator (2) with a prescribed radial gap (clearance CL1); and an inner frame (3) (support member) for fixedly supporting one end (end in the positive x-axis direction) of the stator (2) in the axial direction to the motor case (4). The inner frame (3) includes: a bolt fastening portion (30) (first coupling portion) coupled to the above-described one end of the stator (2) without being coupled to the motor case (4); a bolt fastening portion (32) (second coupling portion) coupled to the motor case (4) without being coupled to the above-mentioned one end of the stator (2); and a connecting portion (33) that connects the bolt fastening section (30) and the bolt fastening section (32). The radial rigidity (k) at the connection section (33) of the inner frame (3) is configured to be lower than the radial rigidity of a bottom section (4b) (a portion that supports the stator (2) via the inner frame (3)) of the motor case (4).
