The ventilation member (1) has a ventilation path (10) for ventilating between the internal space (2u) and the external space (2s) of the housing (2). The ventilation path (10) is a path for ventilating between the internal space (2u) and the external space (2s) when the ventilation member (1) is attached to the edge (2f). A ventilation member (1) is provided with a support part (12), a ventilation film (11), a protruding part (13), and a sealing member (14). The support part (12) surrounds the air passage (10). The ventilation membrane (11) is fixed to the support part (12), and closes the ventilation path (10) so as to allow ventilation. The protruding portion (13) is formed so as to protrude from the support portion (12) and surround one end of the ventilation path (10), and the protruding portion (13) is a cylindrical portion that comes into contact with the edge (2f) when the ventilation member (1) is attached to the edge (2f). The ventilation member (1) satisfies the condition 0.7 < = D/W < = 1.3.
通气部件(1)具有用于使壳体(2)的内部空间(2u)与外部空间(2s)之间通气的通气路(10)。通气路(10)是用于在通气部件(1)装配于边缘(2f)时使内部空间(2u)与外部空间(2s)之间通气的路径。通气部件(1)具备支承部(12)、通气膜(11)、突出部(13)、密封构件(14)。支承部(12)包围通气路(10)。通气膜(11)固定于支承部(12),并将通气路(10)以能够通气的方式闭塞。突出部(13)以从支承部(12)突出而包围通气路(10)的一端的方式形成,突出部(13)是在通气部件(1)装配于边缘(2f)时与边缘(2f)接触的筒状的部位。通气部件(1)满足0.7≤D/W≤1.3的条件。
