PROBLEM TO BE SOLVED: To provide a device (a pasting material) having an extremely simpler structure than those of conventional percutaneous administration devices of impressing an electric voltage, having a light weight, inexpensive, excellent in portable property and capable of administering an ionic medicine. SOLUTION: This pasting material is provided by using a material obtained by impregnating the ionic medicine for administration in an ion exchanging membrane using a porous film, etc., as a substrate and having≤7μm surface roughness (Rz) of a contacting surface with a living body. Preferably, a material obtained by sealing the ionic medicine in a bag-shaped material consisting of such the ion exchange membrane 2 and a filmy external packing material 4 not penetrating the medicine and a solvent, and closely sealing its peripheral part 6 by hot melting, etc., is used. By using the ion exchange membrane having≤7μm surface roughness (Rz) at the contacting surface with the living body, the medicine infiltrates into the living body without impressing the electric voltage. Since an electric power source and opposing electrodes become not necessary, its structure can be made as very simple and the portable property is extremely improved. COPYRIGHT: (C)2005,JPO&NCIPI
