摘要： A fine porous membrane having a pore size distribution in the thickness direction and having a layer having a minimum pore size in the interior thereof, wherein the ratio of maximum pore size to the average pore size, each as determined according to ASTM-316-80, is not more than 1.8. The fine porous membrane is produced by a process comprising casting a film-forming solution, comprising a polymer in a solvent having incorporated therein a swelling agent and a non-solvent, on a casting carrier while being in a solution state, directing air having a temperature of from 15.degree. to 60.degree. C. and a relative humidity of from 10 to 80% onto the surface of the cast film at a velocity of from 0.2 to 4 m/sec for a period of from 2 to 17 seconds to cause coacervation of the cast film while controlling the evaporation loss of the solvent from the cast film and the absorption of non-solvent vapors in the air, dipping the case film in a coagulating bath to cause phase separation and coagulation to form a fine porous membrane, and stripping off the membrane from the casting carrier. The fine porous membranes has a low filtration resistance, a great filtration flow rate, a high efficiency in trapping fine particles and bacteria, and a long life.
