An iontophoresis device, which can ensure the long-term stability of drugs and which can be easily assembled when used, is provided. A donor electrode-printed portion ( 6 ) is placed on one side of a backing layer ( 4 ), and a reference electrode-printed portion ( 7 ) is placed on the other side. Both printed parts are connected to a current generating part (Ia) through a connector (Id). A drug support film ( 14 ) is joined to a drug-dissolving portion ( 11 ), and a cup-like shaped protective cover ( 12 ), which covers the drug support film ( 14 ), is removed before the device is used. The exposed drug support film ( 14 ) is attached to the skin of a user, and the device is driven by turning on a power supply of the current-generating portion (Ia). |
