Claim:
1. A rotating electric machine comprising: a rotor supported being rotationally movable; a stator including an inner circumferential face opposing to an outer circumferential face of the rotor by means of a gap therebetween; a frame accommodating in an interior thereof the rotor and the stator, and also sealing in the interior a cooling fluid that cools the rotor and the stator; at least one cooling fluid duct mounted in a protruding portion on an outer periphery of the frame, communicating with an interior of the frame, the outer periphery facing away from an outer circumferential face of the stator; and at least one cooling device placed in the at least one cooling fluid duct, for cooling the cooling fluid; the rotating electric machine characterized in that the at least one cooling device includes a first end-face portion through which the cooling fluid flows into the at least one cooling device, and a second end-face portion formed at a position opposing to the first end-face portion, for flowing the cooling fluid, being cooled, out of the at least one cooling device; and at least one of the following first item (1) and second item (2) is included: (1) between the first end-face portion and the second end-face portion, at least one of the end-face portions is placed tilting with respect to a minimum-width's direction of the at least one cooling fluid duct adjacent to the at least one cooling device; and (2) between the first end-face portion and the second end-face portion, at least one of the end-face portions is placed tilting with respect to at least one of an inflow direction of the cooling fluid and an outflow direction of the cooling fluid.
