description To improve separation selectivity between light gases such as hydrogen and helium, and other kinds of gases such as, carbon dioxide, oxygen, nitrogen and methane.SOLUTION: There is provided a gas separation composite membrane comprising at least: a porous support layer; and a separation function layer provided on the porous support layer. In the porous support layer and/or the separation function layer, an inhibitor for inhibiting passage of gas is included, and the inhibitor is selected from the group consisting of a surface active agent and an organic silicon compound.SELECTED DRAWING: Figure 1 【課題】水素およびヘリウム等の軽ガスと二酸化炭素、酸素、窒素、メタン等の他種ガスとの分離選択性を向上させる。【解決手段】少なくとも多孔性支持層、及び前記多孔性支持層上に配置された分離機能層を有する気体分離用複合膜であって、前記多孔性支持層及び／又は分離機能層中には、気体の透過を阻害する阻害剤を含み、前記阻害剤が、界面活性剤及び有機ケイ素化合物からなる群より選択される、気体分離用複合膜。【選択図】図１
