Abstract
An automotive alternator includes: a case; a shaft; a rotor that is fixed to the shaft; a stator that is fixed to an inner wall surface of the case; and a rectifier apparatus that is disposed inside the case and that is electrically connected to a stator coil of the stator so as to rectify alternating current generated in the stator coil into direct current, the rectifier apparatus having: a heatsink; diodes; and a circuit board that connects the diodes and the stator coil electrically and that is fixed to the case so as to be supported together with the heatsink by mount portions at three points, the alternator being characterized in that: vibration suppressing portions that are thicker than the mount portions and that suppress generation of vibrational modes in the circuit board among the mount portions are disposed on the mount portions.
