Summary:Provided is a porous membrane combining virus removal performance and permeability. This porous membrane has an average minor axis pore diameter on at least one surface of 10nm to 90nm, a film thickness of 60μm to 300μm, and the absorption capacity of the porous membrane as a whole with respect to the bacteriophage MS2 is at least 8 × 109PFU/g. L'invention concerne une membrane poreuse combinant performance d'élimination de virus et perméabilité. Cette membrane poreuse possède un diamètre des pores d'axe mineur moyen sur au moins une surface de 10nm à 90nm, une épaisseur de film de 60μm à 300μm, la capacité d'absorption de la membrane poreuse comme un tout par rapport au bactériophage MS2 étant d'au moins 8 × 109PFU/g. 本発明の目的はウイルス除去性能と透水性能を両立した多孔質膜を提供することにある。本発明に係る多孔質膜は、少なくとも一方の表面において孔の短径の平均値が10nm以上90nm以下であり、膜厚が60μm以上300μm以下であり、多孔質膜全体のバクテリオファージMS2に対する吸着能が8×109PFU/g以上である。
