PROBLEM TO BE SOLVED: To increase the transmission amount of medicine ions to skin by raising adhesiveness between the skin and an ion selection film. SOLUTION: An iontophoresis apparatus 10 comprises: a DC power source 12; an action side electrode structural body 20 connected to the anode or cathode of the DC current power source; and a non-action side electrode structural body 40 connected to the other, for administering the medicine ions held by the action side electrode structural body to a living body with a voltage from the current power source. The action side electrode structural body includes at least: an action side electrode 24 connected to the anode or cathode with polarity being the same as that of the medicine ion; a chemical liquid holding part 30 electrically connected to the action side electrode so as to hold the medicine to be the medicine ion; and an action side ion selection film 32 electrically connected to the chemical liquid holding part so as to selectively pass the ion being the same in kind as the medicine ion. When the iontophoresis apparatus is mounted on the skin of the living body, a viscous liquid 70 is held between the action side ion selection film 32 and the skin. COPYRIGHT: (C)2008,JPO&INPIT
