PROBLEM TO BE SOLVED: To provide a high performance blood purifying membrane which is extremely little in elution from the membrane, hardly causes sticking of blood protein and blood platelets thereto and has excellent dialysis performance and a producing method thereof. SOLUTION: This method for producing hollow fiber type blood purifying membrane features that the wet membrane where a pore retaining agent is not incorporated, water permeability of pure water is >=100 mL/m<2> .hr.mmHg, permeability of polyvinyl pyrrolidone of weight average molecular weight 40,000 is >75% and permeability of albumin in bovine blood plasma is >=0.3% is dried at a temperature of <=120 deg.C.
