Zusammenfassung:	To provide a surface modification porous film excellent in durability, and having a function imparted thereto by introducing a functional polymer layer simply to the surface of the porous film.SOLUTION: In a surface modification porous film comprising a porous film, and a functional polymer layer formed on the porous film surface, the functional polymer layer contains a functional unit containing an anionic group, and a 5-30 mol% secondary amino group unit. The surface modification porous film is obtained, in which a film surface zeta potential is -20 to -50 mV, and stain resistance and fouling resistance are improved, and high function and durability are imparted.SELECTED DRAWING: None 【課題】多孔質膜の表面に簡便に機能性ポリマー層を導入して機能を付与するとともに、耐久性にも優れた表面修飾多孔質膜の提供。【解決手段】多孔質膜と、多孔質膜表面に形成された機能性ポリマー層とからなり、前記機能性ポリマー層がアニオン性基を含む機能性単位および５〜３０モル％の二級アミノ基単位を含む表面修飾多孔質膜とすることで、膜表面ゼータ電位を−２０〜−５０ｍＶとし、耐汚染性、ファウリング耐性を向上し高機能と耐久性を付与した表面修飾多孔質膜。【選択図】なし
