PROBLEM TO BE SOLVED: To provide a gas permeable member and so forth in which a gas permeable sheet can be easily fitted to a container body and is hardly detached from the container body.SOLUTION: A gas permeable member comprises: a gas permeable sheet which allows gas to permeate; and a holder which holds the gas permeable sheet. The gas permeable member is inserted into a container body via a through-hole opened on the surface of the container body and communicating with an interior space. In this way, the gas permeable member is fitted so as to allow ventilation between the interior space and an exterior space of the container body via the gas permeable sheet. The gas permeable member further comprises a pressing part which is in contact with an inner wall of the through-hole, and which presses, at the contact position, against the inner wall toward the opening side when force is applied in a direction to pull it out from the opening side. 【課題】容器本体への気体透過シートの取り付けが容易にでき且つ容器本体からはずれにくい気体透過部材等を提供することを課題とする。【解決手段】気体を透過する気体透過シートと、前記気体透過シートを保持する保持体とを備え、内部空間と連通する貫通孔が表面に開口している容器本体に、前記開口から挿入されることで前記気体透過シートを介して前記内部空間と前記容器本体の外部空間との間で通気を行うように取り付けられる気体透過部材であって、前記気体透過部材は、前記貫通孔の内壁上に接触し、且つ、開口側から引き抜く方向に力が加わった際に接触位置において前記内壁上を前記開口側に向かって押圧する押圧部を更に備えている気体透過部材等である。【選択図】図１
