摘要： Methods of producing a deformed porous hollow fiber membrane by thermally induced phase separation, particularly by discharging a fusion kneaded product containing a thermoplastic resin and an organic liquid through an orifice of a hollow fiber-forming deformed nozzle; cooling and solidifying the fusion kneaded product discharged through the deformed nozzle to form the product into a hollow fiber-like material having a deformed cross section at a cross section vertical to a discharging direction; and extracting away the organic liquid from the hollow fiber-like material to obtain the deformed porous hollow fiber membrane, wherein an inorganic fine powder is kneaded in the fusion kneaded product.
