Abstract
An iontophoresis device useful for administering an ionic drug by iontophoresis has an iontophoresis electrode section (active electrode section) and a ground electrode section (inactive electrode section) both of which are to be connected to a power source. The iontophoresis device includes elements (members) of both of the electrode sections are all formed of membrane bodies, and includes ion exchange membranes different in ion selectivity, one being selective to ions of the same species as charged ions of the ionic drug and the other to ions different in species from the charged ions of the ionic drug that are arranged in the iontophoresis electrode section, and at least an ion exchange membrane selective to ions opposite to the charged ions of the ionic drug is arranged in the ground electrode section. The iontophoresis device can administer the ionic drug stably over a long period of time at high transport efficiency.
