PROBLEM TO BE SOLVED: To provide a method for producing a hollow fiber membrane for blood purification, which is excellent thread sliding property and to provide a hollow fiber membrane excellent in spinning yield and module production yield. SOLUTION: In the hollow fiber membrane for blood purification, a coefficient of static friction and a coefficient of kinetic friction between hollow fiber membranes are within a predetermined range. In the method for producing a hollow fiber membrane for blood purification, a hollow fiber membrane is produced by dry-wet spinning method. In the method, drying and cooling steps are carried out just before winding the hollow fiber membrane around a bobbin. COPYRIGHT: (C)2008,JPO&INPIT
