Abstract
A ventilation member () of the invention includes a tubular part (), a gas permeable filter (), and a cover part (). In an attached state where the tubular part () is fit into the cover part (), gaps functioning as gas passages (ARand AR) are formed between a bottom portion () of the cover part () and the gas permeable filter () and between a side wall portion () of the cover part () and a body portion () of the tubular part (). The opening area (S2) of a filter-end opening () with respect to an in-plane direction (WL) perpendicular to the thickness direction of the gas permeable filter () is larger than the opening area (S1) of a connection-end opening () with respect to the in-plane direction (WL).
