PROBLEM TO BE SOLVED: To improve an administration efficiency in an ion-tophoretic apparatus for administering a medicinal ion to an organism through an ion exchange membrane. SOLUTION: This ion-tophoretic apparatus includes a working electrode structure having a first porous film having a large number of pores, which communicate between the frontside surface and the backside surface, a first ion exchange membrane, formed of an ion exchange resin filled into the pores in the first porous film, for selecting a first conductivity type ion, and a medicine holding part disposed on the backside of the ion exchange membrane, for holding a medicinal liquid containing a medicinal ion electrified in the first conductivity type. In the ion-tophoretic apparatus where the medicinal ion is administered through the first ion exchange membrane, a layer of a water soluble polymer compound chemically bonded to a material constituting the first porous film is formed on the surface of the first porous film.
