摘要:
A through hole (50) with an annular groove (52) provided about its periphery is formed in a resin case (10). The through hole (10) is covered with a water/oil-repellent film (40) comprising a porous film (44). The through hole (50) makes the resin case (10) gas-permeable, and the water/oil-replacement film (40) prevents entry of external water and oil, etc.
