PROBLEM TO BE SOLVED: To provide a medical blood purifier of hollow fiber membrane type, excellent in the safety and module assembling properties, with high water permeability to be used in the therapy of chronic renal failure. SOLUTION: The blood purifier comprises a hydrophobic polymer hollow fiber membrane including a hydrophilic polymer, wherein elusion of the hydrophilic polymer from the hollow fiber membrane is not more than 10 ppm, the ratio of presence of the hydrophilic polymer in the outer surface of the hollow fiber membrane is 25-50 mass%, and the burst pressure is at least 0.5 MPa. The highly water-permeable blood purifier of hollow fiber membrane type is characterized by the water permeability which is at least 150 ml/m2/hr/mmHg. COPYRIGHT: (C)2006,JPO&NCIPI
