An alternator has a rectifier converting an alternating current to a direct current. The rectifier has a heat sink and rectifying elements. The sink has front and rear surfaces opposite to each other along a depth direction. The sink has holes each extending along the depth direction. Each element has a disk disposed in one hole and a semiconductor pellet attached to the disk. Each disk has upper and bottom surfaces opposite to each other along the depth direction. Each pellet is disposed on the upper surface. A contact surface of each disk is in contact with the sink. A position of the upper surface of each disk is placed between the first and second surfaces of the heat sink. A range of the contact surface of each disk is within a range between the upper and bottom surfaces of the disk.
