Procedure

Polyethersulfone (SUMIKAEXCEL®4800P, manufactured by Sumika Chem Tex Co., Ltd.) (20 mass %), triethyleneglycol (manufactured by MISTUI CHEMICALS, INC.) (40 mass %), and N-methyl 2-pyrrolidone (manufactured by Mitsubishi Chemical Corporation) (40 mass %) were mixed and stirred to prepare a homogeneous and transparent membrane-forming solution. A hollow fiber membrane was obtained in the same manner as in Example 2, except that this membrane-forming solution and N-methyl 2-pyrrolidone/triethyleneglycol/water (=5/5/90) as a void-forming material were used. The inner diameter of the hollow fiber membrane was 195 μm; the thickness thereof was 51.5 μm; the moisture content thereof was 0.4 mass %; and the mass ratio of the hydrophilic polymer was 0 mass %.
