The invention provides a device for a percutaneous absorption preparation, provided with a solution storage container which can exhibit good solution migration independently of the level of force. The device for a percutaneous absorption preparation comprises an electrode film comprising a base member (1) and an electrode layer (2) and having a dissolution liquid passage hole (9), a drug impregnation member (3) mounted on the electrode layer (2) side of the electrode film, and a dissolution liquid storage container (5) bonded to the base member (1) side of the electrode film via a lid member (7) covering the solution passage hole (9). The dissolution liquid storage container (5) comprises a bottom and a sidewall. A protrusion (5b) which faces the dissolution liquid passage hole (9) is provided at the center of the bottom, and the sidewall is provided with a vertically folded part (5c).
