DEVICE FOR TRANSDERMAL PREPARATION

摘要

To provide an easily producible mass-production type transdermal drug device having a structure that a dissolution liquid and a drug can be mixed by simple operations. The device comprises an electrode holder (1) having an electrode layer (1b) formed on a substrate (1a), a drug-loaded member (2) provided on a surface of the electrode holder (1) for forming the electrode layer (1b), and a dissolution liquid-storing container (5) provided on a surface of the electrode holder (1) for not forming the electrode layer (1b), wherein a dissolution liquid passing hole (8) is formed in the electrode holder (1), a flange (5a) of the dissolution liquid-storing container (5) is bonded to the electrode holder (1) via a lid material (6) covering the dissolution liquid passing hole (8), the dissolution liquid-storing container (5) has a protrusion (5b) opposing the dissolution liquid passing hole (8), and the protrusion (5b) has a recessed surface at the tip.
