摘要： An alternator (3) includes MOSFETs (51-56) used as rectifiers which are sealed by a sealing member (72, 74) (for example, a molded epoxy resin) together with heat radiating fins (42, 43) and an external input/output terminal plate (44). The sealing member (72, 74) can evenly dissipate stress even if the radiating fins (42, 43), terminal plate (44), and the like vibrate with different phases. Since the rectifying elements (51-56) are reliably secured even when subjected to great vibrations, damage to the MOSFETs (51-56) can be suppressed. The MOSFETs (51-56) are never exposed to atmospheric air since the MOSFETs (51-56) are sealed by the sealing member (72, 74). Therefore, the alternator (3) can improve the MOSFETs' (51-56) resistance against adverse operational conditions.
