Beschreibung
Zusammenfassung:	A ventilation component 1 includes a ventilation path 10 for allowing ventilation between an inner space 2u and an outer space 2s of a housing 2. The ventilation path 10 is a path for allowing ventilation between the internal space 2u and the outer space 2s when the ventilation component 1 is attached to an edge 2f. The ventilation component 1 includes a supporting portion 12, a gas-permeable membrane 11, a protruding portion 13, and a sealing member 14. The supporting portion 12 surrounds the ventilation path 10. The gas-permeable membrane 11 is bonded to the supporting portion 12 and closes the ventilation path 10 in a ventilatable manner. The protruding portion 13 is a part having a tubular shape, the part being arranged to protrude from the supporting portion 12 and surround one end of the ventilation path 10, the part being configured to be in contact with the edge 2f when the ventilation component 1 is attached to the edge 2f. The ventilation component 1 satisfies requirements 2.5≤Gs/Gt≤5.0 and 1.0≤{(Gs−Gt)/2}/Lt≤3.0.
