    Abstract: A waterproof sound-transmitting membrane of the present disclosure includes: a non-porous resin film having formed therein a plurality of through holes extending through a thickness of the non-porous resin film; and a liquid-repellent layer formed on a principal surface of the resin film and having openings at positions corresponding to positions of the plurality of through holes. The through holes have a diameter of 4.0 μm or more and 12.0 μm or less, and the waterproof sound-transmitting membrane has a through-thickness air permeability of 2.0 cm3/(cm2·second) or more and 50 cm3/(cm2·second) or less in terms of Frazier number as measured according to JIS L 1096. With this waterproof sound-transmitting membrane placed over an opening of a housing of an electronic device or the like, entry of water into the housing from outside can be prevented, in addition to which the characteristics of sound transmitted through the membrane can be kept even when the membrane has a reduced effective area.

    Abstract translation: 本公开的防水透声膜包括：无孔树脂膜，其中形成有多个贯穿所述无孔树脂膜的厚度的通孔; 以及形成在所述树脂膜的主表面上并且在与所述多个通孔的位置对应的位置处具有开口的疏液层。 通孔的直径为4.0μm以上且12.0μm以下，防水透声膜的透气度为2.0cm 3 /（cm 2·秒）以上且50cm 3 /（cm 2·秒以下） ）以下，根据JIS L 1096测定的Frazier数量。通过将该防水透声膜放置在电子设备等的壳体的开口上，可以防止水从外部进入壳体， 此外，即使当膜具有减小的有效面积时，也可以保持透过膜的声音的特性。

    Abstract: A ventilation member (100) of the invention includes a tubular part (11), a gas permeable filter (19), and a cover part (31). In an attached state where the tubular part (11) is fit into the cover part (31), gaps functioning as gas passages (AR2 and AR3) are formed between a bottom portion (35) of the cover part (31) and the gas permeable filter (19) and between a side wall portion (39) of the cover part (31) and a body portion (17) of the tubular part (11). The opening area (S2) of a filter-end opening (15) with respect to an in-plane direction (WL) perpendicular to the thickness direction of the gas permeable filter (19) is larger than the opening area (S1) of a connection-end opening (13) with respect to the in-plane direction (WL).
