An alternator for vehicle includes a stator that outputs an AC voltage and a rotor that includes a field coil and a rotor core. The stator includes a plurality of phase stators that are disposed side-by-side along the rotational axis and individually output AC voltages. The phase stators include an even number of stator tabs alternately extending from one outer side of a phase stator coil toward another outer side of the phase stator coil and extending from the other outer side toward the one outer side along the rotational axis. The rotor includes a field coil and a rotor core at which an even number of rotor tabs are formed along the circumferential direction so as to alternately extend from one outer side of the field coil toward another outer side of the field coil along the rotational axis and extend from the other outer side toward the one outer side along the rotational axis. A phase stator core at each phase stator is formed by laminating a plurality of magnetic sheets.
