This vent member is provided with: a permeable member provided with a permeable sheet material which selectively allows a specific gas to pass therethrough, and a first frame for supporting peripheral edge portions of the permeable sheet material; and a protective member provided with a protective sheet material, and a second frame for supporting peripheral edge portions of the protective sheet material. The permeable member and the protective member are integrally configured by coupling the first frame and the second frame. The protective sheet material is configured so as to be provided to at least one surface side of the permeable sheet material.
