ELECTRONIC CONTROL DEVICE

摘要

The problem of the present invention is to efficiently cool an electronic component with a heating property with air inputted from the outside. A case (2) of an electronic control device (1) includes a case member (4) which maintains a circuit board (3) and a cover member (5) which covers the circuit board (3) maintained on the case member (4). A ventilation path (13) to connect the inside and the outside of the case (2) is formed on the case member (4). An opening part (15) of one end of the ventilation path (13) is formed on a position facing the leading end of a heating component (12) mounted on the circuit board (3). A standing wall (14) to protrude to the heating component (12) is formed on the outer edge of the opening part (15) of one end of the ventilation path (13). Thereby, the heating component is efficiently cooled by guiding the air inputted from the ventilation path (13) which connects the inside and the outside of the case (2) by the standing wall (14) to the heating component (12).
