Abstract
An electronic control device includes a conductive casing; a circuit board which is provided in the casing, and on which an electronic component including an integrated circuit is mounted; and a conductive conductor component that is provided on the circuit board, is disposed at a position higher than the electronic component, and has an elongated shape, in which a distance between the conductor component and the casing is shorter than a distance between the conductor component and the circuit board.
Claims17
An electronic control device comprising:
- a conductive casing including an upper portion and a lower portion forming a gap;
- a circuit board which is provided in the casing, and on which an electronic component including an integrated circuit is mounted;
- an external connection terminal that is provided on the circuit board and is formed through the gap;
- and
- a conductive conductor component that is provided on the circuit board, is disposed at a position higher than the electronic component, and has an elongated shape, the conductive conductor component configured to suppress an electric field between the circuit board and the conductive conductor, the electric field generated due to electromagnetic wave noise passing through the gap, wherein a width of the conductive conductor component is smaller than a width of the integrated circuit,
- wherein a distance between the conductor component and the casing is shorter than a distance between the conductor component and the circuit board.
