PROBLEM TO BE SOLVED: To provide a waterproof housing and a waterproof device capable of effectively suppressing peeling of a sheet-like filter by a high pressure water flow.SOLUTION: The waterproof housing for housing an electric component includes a through-hole for ventilation and a sticking part where a sheet-like filter is stuck so as to cover the through-hole, and a wall surface part configuring the through-hole includes a first slope part having such inclination that an opening area of the through-hole is larger as separating from an inner surface of the waterproof housing in a through direction of the through-hole. Also, the sticking part of the filter is provided on a part further from an outer surface than the first slope part in the through direction. Then, as the first slope part, the inclination is provided such that the change amount of the opening area is larger as approaching the filter in the through direction. |
