Abstract: An electronic control device includes a non-conductive resin housing; a circuit board; a metal housing; a waterproof seal material; and a conductive adhesive. The circuit board has a circuit ground (GND pattern), and is held by the resin housing. The metal housing covers the circuit board and is attached to the resin housing. The waterproof seal material seals and waterproofs the resin housing and the metal housing. The conductive adhesive is in contact with the metal housing and the circuit ground, and electrically connects the metal housing to the circuit ground at a plurality of points.

Abstract: In order to prevent a short-circuit failure between a conductive connecting portion (1) that is provided as a countermeasure against external electrical noises and an electronic circuit, a structure is adopted where a large number of electronic components (8) are mounted on a circuit board (5) that is mounted on a base (7), a metal cover (6) is disposed so as to cover upper portions of the electronic components (8), opening portions (3) are formed in the circuit board (5) at four positions on a periphery of the circuit board (5), protruding members (12) that are integrally formed with the base (7) are disposed at four positions respectively in alignment with the positions where the opening portions (3) are formed, the protruding members (12) are made to pass through the opening portions (3) at four positions from a back surface side of the circuit board (5) to protrude to a front surface side of the circuit board 5, the conductive connecting portions (1) are arranged in an outside direction with respect to the protruding members (12) at four positions on the board, the protruding members (12) are disposed between the conductive connecting portions (1) and the electronic circuit so as to electrically connect the metal cover (6), the conductive connecting portion (1), and a ground circuit to each other.
