摘要：
An iontophoresis device which allows excellent transdermal absorption of an anionically chargeable physiologically active substance is provided. The iontophoresis device comprises a cathode (25) and an interface (31) or (32) composed of a cationically chargeable membrane, wherein an anionically chargeable physiologically active substance (drug) (10) is placed between the cathode (25) and the interface (31) or in the interface (32). A wall member (13) with an adhesive layer (12) in the bottom is placed around an absorbent (11), and a support (15) having an opening (14) in the center is placed on the absorbent (11) and the wall member (13). When the device is used, the dissolution liquid for the drug is supplied to the absorbent (11) through the opening (14). The absorbent (11) and the interface (31) or (32) become wet with the dissolution liquid and the drug (10) is activated uniformly.
