A ventilation member (1A) includes a wall portion (2a), an attachment portion (2b), and a plurality of recessed portions (2d). The wall portion (2a) is formed to define the recessed portions (2d) and is configured to allow a gas to pass through between its inner surface facing the recessed portions (2d) and its outer surface opposite to the inner surface. The attachment portion (2b) is formed to extend outwardly around a rectangular opening (2c) and provides an attachment surface adapted to be attached to a housing (50) that needs to be ventilated. The ventilation member (1A) is a member formed of a porous resin, and at least the wall portion (2a) and the attachment portion (2b) are integrally formed. |
