번잡하지 않은 공정으로 제조할 수 있고, 높은 친수성과 투수성을 갖고, 막 분리 활성 오니법(MBR법)에 사용했을 때의 내파울링성이 우수한 다공질막을 제공한다. 폴리머 (A) 및 폴리머 (B)를 포함하는 다공질막으로서, 폴리머 (A)는 막 형성 폴리머이고, 폴리머 (B)는 식 (1)로 표시되는 단위 (b1) 및 수산기 함유 (메트)아크릴레이트에 기초하는 단위 (b2)를 갖는 폴리머이고, 다공질막 중 단위 (b1)의 농도(질량%)가 단위 (b2)의 농도(질량%) 이상인 다공질막. Provided is a porous membrane that can be manufactured in uncomplicated steps, has high hydrophilicity and water permeability, and exhibits excellent anti-fouling properties when used in a membrane bioreactor method (MBR method). The porous membrane of the present invention is a porous membrane containing polymer (A) and polymer (B), wherein the polymer (A) is a membrane-forming polymer, the polymer (B) is a polymer having a unit (b1) represented by formula (1) and a unit (b2) based on hydroxyl group-containing (meth)acrylate, and the concentration (mass%) of the unit (b1) is equal to or higher than the concentration (mass%) of the unit (b2) in the porous membrane.
