There is provided a method for continuous production of a functional membrane whereby a functional membrane in which a functional polymer is filled into the micropores of a porous resin sheet can be obtained both continuously and efficiently. The method for continuous production of a functional membrane of the present invention comprises a step for impregnating and depositing a polymer precursor (2-acrylamido-2-methylpropane sulfonic acid or the like) having a functional group on a continuously conveyed porous resin sheet (a porous polyethylene sheet or the like); a polymerization step for continuously feeding and bringing into contact first and second resin films (both films comprising polyester films or the like) to one side and the other side, respectively, of the precursor-impregnated/deposited sheet comprising the porous resin sheet into which the polymer precursor is impregnated and deposited, and polymerizing (by irradiation with active energy rays, or by another method) the polymer precursor in a state in which the sheet is sandwiched between the two resin films; a film peeling step; and a polymer removal step.
