Abstract
Depending on the orientation by which a breathing filter is mounted in a vehicle, water can accumulate in the breathing filter, and prevent the pressure difference between the space inside a case and the outside air from being adjusted; therefore, the vehicular layout is limited. Also, because the filter is formed in the center of the case, electronic parts cannot be installed on substrates on the upper and lower surfaces of the filter, meaning that the substrate size and the case size will increase. In addition, the costs will increase. The structure of the present invention is characterized in that breathing paths are provided on the surfaces sandwiching a portion where a filter film is welded in the corner of a resin-side case of a vehicle-mounted electronic control device such as an engine control unit or an automatic transmission control unit, and in that the breathing paths are connected inside.
