Abstract
An iontophoresis device including an active electrode assembly or a counter electrode assembly with a polarizable electrode containing any one of a conductive material having a capacitance per unit weight of 1 F/g or greater, a conductive material having a specific surface area of 10 m2/g or greater, and activated carbon is disclosed. The generation of gas or ions due to an electrode reaction occurring in an electrode assembly may be reduced or prevented. In addition, the alteration of an active agent due to a chemical reaction upon energization may be reduced or prevented.
