Abstract
A circuit board is sealed and housed in a casing including a base and a cover, a connector housing including a partition wall is mounted on the circuit board, and an electrical connection between the interior and the exterior of the casing is established. A water-repellent filter is fixed to an inner surface of the partition wall, an outer surface portion of the water-repellent filter is opened to atmosphere via the breath ventilation hole, and an atmospheric opening surface thereof is formed such that the atmospheric opening surface being wetted directly with water is avoided by a poured water blocking wall and water barrier walls. A position where the poured water blocking wall is provided is changed by an insert mold in response to the direction of the mounting surface of the base.
