Abstract
It is intended to provide a blood purification membrane having excellent performance and showing little elution of blood and little adhesion of blood proteins or platelets. The above object can be achieved by using a moisten membrane, which is free from any membrane pore-sustaining agent and has a high water permeation dose and a large pore size, and lessening the pore size by drying the membrane after desolvation.
