(57) [Abstract] [Object] The present invention prevents deterioration of appearance, staining of clothes, and decrease in drug use efficiency due to the drug in the pressure-sensitive adhesive layer seeping out of the support, and particularly, By adjusting the moisture permeability of the porous synthetic resin film, it is possible to suppress the evaporation of water and volatile components in the pressure-sensitive adhesive layer, to maintain a therapeutic effect, a cooling effect, or a compressing effect over a long period of time. An object of the present invention is to provide an external patch which prevents the occurrence of skin irritation such as rash, itch, and red spots to thereby greatly improve safety and hygiene, and which further improves the feeling of use. The present invention relates to a skin-adhesive patch in which a pressure-sensitive adhesive layer is laminated on one side of a film-shaped or sheet-shaped support, wherein the support is a porous synthetic resin film having fine pores , And has a moisture permeability in the range of 500 to 7,000 g / m 2 ยท 24 hr. |
