Abstract
A waterproof case for housing an electronic component includes a case member that has a plurality of breathing holes, and a breathable waterproof filter fitted to the case member at a position corresponding to the breathing holes to cover the breathing holes. For example, open surfaces of at least two of the breathing holes, opened outside of the case member, can be made to face in different directions. Furthermore, the breathing hole has an open area on a side of the breathable waterproof filter, which is larger than an open area of the breathing hole on a side opposite to the breathable waterproof filter, in the case member. Accordingly, the waterproof case enhances waterproofness while circulating air between the inside and the outside of the waterproof case.
