Patent ID: 8717766

Claim:
A resin-sealed electronic controller, comprising: a circuit board on which a plurality of circuit components are mounted; a thermally-conductive base plate bonded to the circuit board; a plurality of external connection terminals connected to the circuit board; and a molding resin for covering the entire circuit board and a part of the external connection terminals and the base plate to form outer covering material portions, the resin-sealed electronic controller being formed by integral molding with the molding resin, wherein: the base plate includes a central window hole formed in a middle portion, a first exposed portion and a second exposed portion exposed to exterior and fixed to mounting portions, and an adjacent flat portion adjacent to the central window hole formed in the middle portion adjacent to the central window hole, which is covered with the molding resin; the circuit board includes a first board surface on which the first circuit components are mounted so as to be located in the central window hole, and a second board surface corresponding to a rear surface of the first board surface, on which the second circuit components are mounted in an area opposed to the adjacent flat portion; the external connection terminals are connected to terminal connection electrodes provided on the second board surface; and the second circuit components are heat-generating components having a smaller height than a height of the first circuit components.
