IONTOPHORESIS DEVICE

PROBLEM TO BE SOLVED: To provide an iontophoresis device excellent in portability capable of suppressing the deterioration of an electrode before use.SOLUTION: An iontophoresis device 1 includes: a base material 2; a pair of electrodes 4a and 4b disposed on the base material 2; a photovoltaic 5 provided on the base material 2 for receiving light and applying a voltage generated to the pair of the electrodes 4a and 4b; and a removable light blocking member 8 for the light blocking for a light receiving surface 7 of the photovoltaic 5. The light blocking member 8 may be a light blocking film 8A that is bonded on the light receiving surface 7 of the photovoltaic 5 or on the light receiving surface 7 side of the photovoltaic 5, or may be a light blocking container for accommodating the iontophoresis device 1. The pair of the electrodes 4a and 4b, and the photovoltaic 5 may be disposed on the different surface of the base material 2, or may be disposed on the same surface of the base material 2.
