Abstract
According to the invention, a patch provided with a support 1, an adhesive layer 2 laminated on one side of the support, and a release film 4 attached in a releasable manner to the adhesive layer and having a slit 42 running from one edge to the opposite edge, is characterized in that the shape of the slit in the release film is a wave shape such that, by simply bending the support slightly along the slit while the exposed side of the adhesive layer which has been exposed by peeling off part of the release film along the slit is attached to the attachment site, the edge 44 of the slit of the remaining release film can promptly protrude outward from between the attachment site and the adhesive layer.
