Summary:To provide a gas separation membrane that includes a gas separation active layer on a porous support body including a pore with a large surface pore diameter, has a high separation coefficient and a high permeability coefficient and can be manufactured by an application method.SOLUTION: A gas separation membrane includes: a porous support body; and a gas separation active layer disposed on the porous support body. The porous support body has a chloroform contact angle of 10° or more and 90° or less.SELECTED DRAWING: Figure 1 【課題】表面孔径の大きな細孔を有する多孔性支持体上に、ガス分離活性層を有するガス分離膜であって、分離係数及び透過係数が高く、塗布法によって製造することができる、ガス分離膜を提供すること。【解決手段】多孔性支持体と、前記多孔性支持体上に配置されたガス分離活性層とを有するガス分離膜であって、多孔性支持体のクロロホルム接触角が、１０°以上９０°以下である、ガス分離膜。【選択図】図１
