PROBLEM TO BE SOLVED: To provide a large-output and small and light dynamo-electric machine, while avoiding the temperature rise of a stator coil. SOLUTION: At least the coil end 2d of a stator coil is constituted by laying each axial projection, consisting of a conductor in the shape of a thin plate projecting from the end plate of a stator core in an attitude that the thickness direction is in matching with the diametrical direction of the stator core 1 on top of the other each in diametrical direction. The cooling capacity of the coil end part 2d is raised by providing the dynamo-electric machine with cooling members 8 and 9 of food thermal conductivity which have flat cooling faces sticking fast directly, while being electrically insulated, to the flat main face of the thin plate-shaped conductor on the outermost side diametrical direction or innermost side diametrical direction of this coil end 2d.
