A rotary electric machine, for solving problems that a space for installing the noise insulation enclosure around the rotary electric machine and a base for installing the noise insulation enclosure are necessary, and that the noise insulation enclosure reducing the noise on an outer side of the noise insulation enclosure does not reduce the noise on an inner side thereof, and the inspecting worker entering thereinto is exposed to a loud noise of the rotary electric machine, the rotary electric machine comprising a stator frame having a stator iron core incorporating a stator coil therein in an inner portion thereof, and a rotor in which a rotor coil rotating so as to oppose to the stator frame and the stator iron core is incorporated, further comprising a noise insulation plate fixed to a noise insulation plate attaching seat welded to an outer surface of the stator frame by a bolt and a nut, an elastic body which is provided in a contact portion between the noise insulation plate attaching seat and the noise insulation plate, and a vibration-proofing rubber washer which is provided in a contact portion between the noise insulation plate and the nut.
