description Disclosed are a composition for forming a filtration membrane comprising a vinylidene fluoride-based resin, a polyester-based diluent, a hydrophilic polymer additive, and 2-pyrrolidone, a filtration membrane manufacturing method using the same, and a filtration membrane manufactured therefrom. The present invention has excellent mechanical strength and water permeability. 불화비닐리덴계 수지, 폴리에스테르계 희석제, 친수성 고분자 첨가제 및 2-피롤리돈을 포함하는 여과막 형성용 조성물, 이를 이용한 여과막의 제조방법, 및 이로부터 제조된 여과막이 개시된다.
