In resin-molded engine control unit, a coil (7), an electrolytic capacitor (8), a microprocessor (9), electronic parts and a connector terminal (1, 2) are mounted on a board (5). Inside a cover (6) fixed on the board (5), a resin-free region (12) is formed. The coil (7), the electrolytic capacitor (8) and the microprocessor (9), which should not be sealed with resin (3), are mounted in the resin-free region (12), while the board (5) and the electronic parts which are not capped by the cover (6) are sealed with a resin (3). |
