1. An iontophoresis device, comprising:
- an active electrode assembly comprising;
a first electrode supplied with an electric potential of a first polarity;
an ionic liquid reservoir that holds an ionic liquid in contact with the first electrode; and
an active agent reservoir placed on an outer surface of the ionic liquid reservoir, the active agent reservoir holding active agent ions of the first polarity.

Abstract
An iontophoresis device may be capable of preventing the generation of gas or ions upon energization, and/or may be capable of preventing the alteration of active agent ions due to an electrode reaction. Energization from an electrode to an active agent reservoir may be performed through an ionic liquid. The ionic liquid may include an anion such as PF6-, BF4-, AlCl4-, ClO4-, a hydrogen sulfate ion, bis-trifluoro-alkyl-sulfonyl-imide, or trifluoro-methane-sulfonate, and a cation such as an imidazolium derivative, a pyridinium derivative, a piperidinium derivative, a pyrolidinium derivative, and a tetra-alkyl-ammonium derivative.

24. An iontophoresis device comprising:
-
an active electrode assembly comprising;
a first electrode; and
an active agent reservoir that holds active agent ions of a first polarity, the active agent ions being administered to a living body by an electric potential of a first polarity applied to the first electrode; and
a counter electrode assembly comprising;
a second electrode supplied with an electric potential of a second polarity;
a second ionic liquid reservoir that holds an ionic liquid in contact with the second electrode; and
an electrolyte solution reservoir that holds an electrolyte solution, the electrolyte solution reservoir placed on an outer surface of the second ionic liquid reservoir.
