Abstract
The present invention relates to an iontophoresis device, which can ensure the long-term stability of a drug and makes the operations for assemblage upon application easy as well as a method of assembling the device. A backing layer (4) is provided with a drug-dissolving portion (11) on a donor electrode-printed portion (6) thereof and a drug support (14) removably contacts with the drug-dissolving portion. A liner (12) is disposed on the backing layer on the skin (40) side and this is peeled off upon practical use. An opening (15) is formed on the liner (12) and an opening (5) is formed on an electrode portion (Ib). When assembling the device, these openings coincide with each other to thus easily and precisely dispose the drug support (14) on the drug-dissolving portion (11).
