The ventilation member (10) of the present invention includes: a support (4); and an air-permeable membrane (2) disposed on the support (4). The support (4) includes: a base portion (11) supporting the air-permeable membrane (2); and a leg portion (12) extending from the base portion (11) toward the interior space (22) of a housing (20) and adapted to fix the ventilation member (10) to the opening (21) of the housing (20). The leg portion (12) includes: insertion portions (31) separated from each other in a circumferential direction by slits (32) formed between the insertion portions (31), the insertion portions (31) being adapted to be elastically deformed radially inwardly when the insertion portions (31) are inserted into the opening (21) and then to be fixed to the opening (21); and rounded portions (33) each formed in a region between an inner circumferential surface (31C) of the insertion portion (31) and a circumferential end surface (31D) of the insertion portion (31) at a root (31A) of the insertion portion (31) and having a rounded convex surface. |
