Abstract: An iontophoretic agent delivery device having a simplified structure and ease of manufacture. The device utilizes an electrical pathway comprising a source of electrical energy and an output means. The electrical pathway is disposed upon one of the two sides of a flexible, non-conductive substrate (e.g., a film). The output means of the pathway are connected directly or indirectly, e.g., by means of an electrically conductive adhesive tape, to the remaining components of the device such as current distribution members, lead wires, or electrodes. In this arrangement, the circuit is inverted from that of conventional devices. Economical, reel-to-reel methods of manufacturing a one-sided iontophoretic circuit apparatus of the invention are disclosed.
