PROBLEM TO BE SOLVED: To provide an iontophoresis device capable of administering an identical medical agent with moving on regions to be administered over time. SOLUTION: The iontophoresis device comprises an electric power unit, a medical agent administering means at least including at least three electrode structures connected to the electric power unit, and a current control means to respectively control currents passing through the electrode structures. The medical agent administering means includes at least two first electrode structures to keep the identical ionic medical agent, and at least a second electrode structure as a counter electrode of the first electrode structures not to keep the ionic medical agent. The iontophoresis device can administer the identical medical agent with moving on the regions to be administered over time when the first electrode structures respectively discharge and administer a predetermined amount of the ionic medical agent to a living body in response to the current amount passing from the current control means.
