PROBLEM TO BE SOLVED: To provide a regenerated cellulose membrane for an artificial kidney having high water permeability and good partition characteristics simultaneously and a method for producing the membrane. SOLUTION: The method for producing the regenerated cellulose membrane includes a solidification-regeneration process in which a cellulose solution using a tertiary amine oxide hydrate is immersed in a solidification-regeneration bath, a cleaning process for washing the obtained membrane, a sticking process for sticking a pore diameter maintaining agent to the wet membrane, and a drying process for heat-drying the membrane held free. In the regenerated cellulose membrane for an artificial kidney which is obtained by the method, a pure water permeation speed is 25-100 ml/m2.h.mmHg, at least 0.9 when the molecular weight of the membrane is 1,000, 0.3-0.95 when the molecular weight is 10,000, and 0.4 or below when the molecular weight is 100,000.
