Abstract
Provided are a semiconductor device realized easily at low cost without requiring a complicated manufacturing process, and an alternator using the same. The semiconductor device includes a base having a base seat, a lead having a lead header, and an electronic circuit body, wherein the electronic circuit body is arranged between the base and the lead; the base seat is connected to a first surface of the electronic circuit body; the lead header is connected to a second surface of the electronic circuit body; the electronic circuit body is integrally covered by resin, including a transistor circuit chip having a switching element, a control circuit chip for controlling the switching element, a drain frame, and a source frame; either one of the drain frame and the source frame, and the base are connected; and the other one of the drain frame and the source frame, and the lead are connected.
