PROBLEM TO BE SOLVED: To provide a fluororesin based polymeric separation membrane excellent in separation characteristic, permeability, chemical strength(chemical resistance), physical strength and stain resistance, a membrane module having a polymeric separation membrane, an apparatus for water separation, a separator for electric batteries, a charged membrane, a fuel cell and a membrane for blood purification. SOLUTION: A polymeric separation membrane is comprised of a fluororesin based polymer having a spherical structure and a three-dimensional mesh structure coextensively including a hydrophilic polymer having at least one kind of these selected from a cellulose ester, a fatty acid vinyl ester, vinylpyrolidone, ethylene oxide and propylene glycol. The polymeric separation membrane of this invention is suitably used for a membrane for water treatment, a separator for electric batteries, a charged membrane, a fuel cell and a porous membrane for blood purification.
