摘要：
The present invention provides an iontophoresis device allowing effective and continuous absorption for a long period. The iontophoresis device comprises the first electrode structure (100a) and the second electrode structure (110a) each having a hydrophilic conductive layer (102a, 112a) containing active ingredient and an electrode member (101a, 111a), and a power supply (120a) having polarity inverting means for switching over a current direction between the two electrode structures, wherein at least one of the first and the second electrode structures contains chloride ions and before administration, a chloride-ion content (P mg) is within a range satisfying the following equation: 1.0×(I×T×0.022)≦P wherein T represents a polarity inverting time (min) until polarity is inverted after energization in a certain direction and I represents an average current (mA).
