Abstract
An object is to prevent a water-repellent filter, which performs ventilation between the interior and the exterior of a sealed casing and prevents entry of water, from being wetted directly with water. 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, and an outer surface portion of the water-repellent filter is opened to atmosphere via first and second ventilation holes and first and second connection ventilation holes. Therefore, the water-repellent filter can be avoided from being wetted directly with water.
