A first conductive sheet film is disposed on a partial area of the skin-contact surface of an adhesive member. A conductive matrix is disposed on the first conductive film, the conductive matrix being dispersed with a drug to be permeated through skin. A second conductive film is disposed on the conductive matrix, the second conductive film having a plurality of openings distributed on the surface of the conductive matrix and having a standard single electrode potential lower than that of the first conductive film. An insulating film is disposed between the conductive matrix and the second conductive film in a manner such that an electric short path is not formed between the conductive matrix and the second conductive film. The insulating film has a plurality of openings distributed on the surface of the conductive matrix, and a connection member electrically interconnects the first and second conductive films.
