Abstract: A rotating electric machine includes a rotor, a stator, formed by stacking perforated-disk-shape stator cores, surrounding the rotor, arranged with a gap from the rotor, a first stator cooling duct to allow the cooling gas to flow from an inner side toward outer side of the stator, a second stator cooling duct to allow the cooling gas to flow from an outer side to an inner side of the stator, a plurality of support plates for supporting the stator and providing sectioning between the first and second flow paths, and a flow control part configured to suppress a flow of the cooling gas passing through the gap part where the outer end part of the stator core and the inner end part of the support plate face each other.
