PROBLEM TO BE SOLVED: To provide a hemocatharsis membrane excellent both in substance removing performance and blood compatibility, and a method of manufacturing the same. SOLUTION: A porous membrane is used in the hemocatharsis membrane, and a layer composed of grains made of water-insoluble hydrophilic high molecules is formed in the hemocatharsis membrane. The method of manufacturing the hemocatharsis membrane, in which the porous membrane is used and which has the layer composed of the grains made of water-insoluble hydrophilic high molecules on the surface of a side of the porous membrane in contact with the blood, comprises: a process (A) of forming and coagulating the porous membrane by contacting a membrane manufacturing stock solution including high molecules with a primary coagulation solution including water-insoluble hydrophilic high molecules, and attaching the grains made of water-insoluble hydrophilic high molecules to the surface of the porous membrane; and a process (B) of further coagulating the porous membrane and coagulating the grains by contacting a secondary coagulation solution substantially made of water with the porous membrane.
