A vehicle AC generator includes a pair of front and rear frames fastened by a plurality of stud bolts at peripheral portions thereof, a stator having a multi-phase armature winding supported by the pair of frames, a rotor disposed radially inside the stator, a rectifier unit having a positive cooling fin holding a plurality of positive diodes, a connection member, and a negative cooling fin holding a plurality of negative diodes. The positive cooling fin is fastened by the plurality of stud bolts together with the pair of frames separate from the negative cooling fin, and the connection member is disposed between the positive cooling fin and the negative cooling fin. The connection member has a circuit for electrically connecting the armature winding and the rectifier unit, which is covered by an insulation member.
