통기 부재(1)는, 개구부(50a)에 장착되어 하우징(50)의 내부 공간과 외부 공간 사이의 통기 경로(4)의 일부로서 개구에 방수 통기막이 형성되어 있지 않은 관통 구멍(2a)을 갖는 통형상의 내측 부재(2)와, 내측 부재(2)의 외주부에 장착되어 관통 구멍(2a)의 개구를 덮는 바닥이 있는 통 형상의 외측 부재(3)를 구비하고 있다. 내측 부재(2) 및 외측 부재(3)는 물과의 접촉각이 80도 이상인 소수성 재료에 의해 형성되어 있다. A ventilation member 1 includes: a tubular inner member 2 adapted to be fitted to an opening portion 50a and having a through hole 2a whose opening is not equipped with a waterproof gas-permeable membrane and which serves as a part of a ventilation path 4 between a space inside a housing 50 and a space outside the housing 50; and a tubular outer member 3 having a bottom, fitted around the outer periphery of the inner member 2, and covering the opening of the through hole 2a. The inner member 2 and the outer member 3 are each formed of a hydrophobic material having a contact angle with water of 80 degrees or more.
