  • Publication number: 20090216175
    Abstract: To provide a transdermal administration device capable of increasing the speed at which a drug is transferred into a skin and the amount of the drug to be transferred into the skin. A transdermal administration device is constituted by: an electrode supplied with a voltage of a first conductivity type; an electrolyte solution holding portion holding an electrolyte solution energized by the electrode; and a bipolar membrane that is placed on the front surface side of the electrolyte solution holding portion, and is composed of a first ion exchange membrane that selectively passes an ion of the first conductivity type and a second ion exchange membrane that selectively passes an ion of a second conductivity type.
