Abstract: A rotating electrical machine comprises a stator and a rotor. The rotor includes a rotor iron core in which a permanent magnet is disposed. The rotor iron core comprises a connection part, a plurality of magnetic pole part, a first gap, and a second gap for injection of the adhesive. The connection part is configured to surround a rotational axis. The plurality of magnetic pole parts are provided in an outer portion than the connection part in a radial direction. The first gap is configured to penetrate along an axial direction between the magnetic pole parts in an outer portion than the connection part in the radial direction and in which the permanent magnet is fixed with adhesive. At least one of the second gaps is provided for each of the first gaps in communication with the first gap.
