A ventilation member (300) includes a tubular part (102), in an interior of which a gas passage for an object that needs ventilation is formed, a gas permeable filter (19) attached to the tubular part (102), and a cover part (110) that defines a gap between itself and the gas permeable filter (19) in an attached state where the tubular part (102) is fit inside from a side of the gas permeable filter (19). The gas passage formed in the interior of the tubular part (102) includes a first gas passage that is to communicate directly with an interior space of the object and a second gas passage isolated from the first gas passage, the gas permeable filter (19) is attached to the tubular part (102) so as to close at least an opening (103) on the basis of the first gas passage and a gas is allowed to circulate between the first gas passage and the second gas passage via the gap (TH) and the gas permeable filter (19). |
