Abstract

This ventilation structure 1a comprises a housing 10a and a ventilation component 20a. The housing 10 has a first surface 12 that forms a side surface of a columnar space 11c in an installation hole 11. The ventilation component 20a is mounted in the housing 10a so as to block the installation hole 11. The ventilation component 20a has a ventilation passage 21 between an inside space 15u and an outside space 15s of the housing 10a. A ventilation component 20a comprises a support 23, a ventilation film 22, a projection 24 and a seal member 25. The support 23 surrounds the ventilation passage 21 in a plan view. The projection 24 projects from the support 23 towards the inside space 15u of the housing 10a and is inserted into the installation hole 11. The seal member 25 is positioned on the outer periphery of the projection 24 and seals between the first surface 12 and the projection 24.
