According to the present invention, an alternator includes a rotor, a stator, and at least one cooling fan. The rotor includes a rotary shaft, a field core, and a field coil. The field coil has first and second ends that are opposite to each other in an axial direction of the rotary shaft. The stator includes an armature core and an armature coil. The armature core has first and second ends that are opposite to each other in the axial direction. The first end of the armature core is closer to the first end than the second end of the field coil. An axial distance between the first and second ends of the field coil is less than that between the first and second ends of the armature core. The first end of the field coil protrudes outward from the first end of the armature core in the axial direction.
