To provide a rotating electric machine such as a generator, a motor, etc., which can be efficiently cooled by efficient heat transmission between a stator winding and a frame and enables an output improvement, dimensional reduction, and weight reduction, and to provide its manufacturing method.

The rotating electric machine G has a rotor 7 with permanent magnets 71, a stator core 2 provided around the rotor 7 and fitted to the inside of a frame 1, and the stator winding 3 wound to the stator core 2. Ring-shaped or divided-ring-shaped heat conducting elements 11 and 11A are inserted between the coil ends 3e of the stator winding 3 and the frame 1. A space surrounded by the heat conducting elements 11 and 11A, the coil ends 3e and the frame 1 is solidly filled with thermosetting resin.
