Abstract: To provide a dynamo-electric machine with which it is possible to improve electrical characteristics by reducing the leakage magnetic flux and increasing the effective magnetic flux. In order to achieve this, a magnetic pole head (23) for restraining a field winding (24) is provided with restraining parts (31) for restraining only the coil end (24b) of the field winding (24). The restraining parts (31) are positioned further axially outside or inside than both axial end surfaces (11a) of a stator core (11). The restraining parts (31) have formed thereon: an inclined surface (31a) positioned further radially inside than the radially outside end surface (23a), of the magnetic pole head (23), which radially faces the inner circumferential surface (11b) of the stator core (11); and a step (31b) for linking the radially outside end surface (23a) and the inclined surface (31a) in the radial direction.
