An ion sensor of the type wherein specific type of ion in an aquious solution is measured by potential response. The sensor includes a conductor base (11), and a reversible redox polymer film (13) formed directly on a surface of said conductor base An ion carrier film (13) is formed directly on a surface of said redox polymer film. The carrier film (13) contains an ion carrier substance for allowing the specific type of ions to permeate from the aqueous solution to said polymer film.
