Abstract
A ventilation component () includes a supporting portion (), a gas-permeable membrane (), and a sealing member (). The supporting portion () has a ventilation path () and an annular surface (). When the ventilation component () is attached to a housing (), the ventilation path () extends in a direction perpendicular to an opening plane of an opening (), and extends through the supporting portion (). The annular surface () faces an outer surface () of the housing (), and surrounds the ventilation path () in plan view. The gas-permeable membrane () closes the ventilation path () in a ventilatable manner. The gas-permeable membrane () allows a gas to pass therethrough in a thickness direction of the gas-permeable membrane (). The sealing member () is sandwiched between the outer surface () of the housing () and the annular surface () to seal a gap between the outer surface () of the housing () and the annular surface (). The sealing member () includes at least one selected from the group consisting of a pressure-sensitive adhesive, an adhesive, and a cured product of an adhesive.
