Disclosed is an iontophoresis device, wherein, between an electrolyte solution holding section for holding an electrolyte solution containing an electrolyte dissolved therein which dissociates into a first electrolytic ion exhibiting a first type of electroconductivity in a solution and a second electrolytic ion exhibiting a second type of electroconductivity in a solution and a pharmaceutical solution holding section for holding an pharmaceutical solution containing a medicine dissolved therein which dissociates into a first pharmaceutical ion exhibiting a first type of electroconductivity in a solution and a pharmaceutical counter ion exhibiting a second type of electroconductivity in a solution, there are arranged a first ion exchange membrane allowing selectively an ion exhibiting a second type of electroconductivity to pass through it and a porous separation membrane blocking the passage of a molecule having a molecular weight of a prescribed value or more, and an ion.

L~invention décrit un dispositif d~ionophorèse. Dans ce dispositif, entre une partie destinée à contenir une solution électrolytique contenant elle-même un électrolyte dissous, qui se dissocie en un premier ion électrolytique montrant un premier type d~électroconductivité dans une solution et un second ion électrolytique montrant un second type d~électroconductivité dans une solution, et une partie destinée à contenir une solution pharmaceutique contenant un médicament dissous, qui se dissocie en un premier ion pharmaceutique montrant un premier type d~électroconductivité dans une solution et un contre-ion pharmaceutique montrant un second type d~électroconductivité dans une solution, sont disposés une première membrane d~échange ionique permettant de manière sélective qu~un ion montrant un second type d~électroconductivité la traverse, une membrane poreuse de séparation bloquant le passage d~une molécule ayant un poids moléculaire d~une valeur prescrite ou supérieure, et un ion.
