Claim:
A patch provided with a support, an adhesive layer laminated on one side of said support, and a release film attached in a releasable manner to said adhesive layer and having a slit running from one edge to the opposite edge, the patch being characterized in that the shape of the slit in said release film is a wave shape such that, by simply bending said support slightly along said slit while the exposed side of said adhesive layer which has been exposed by peeling off part of said release film along said slit is attached to the attachment site, the edge of said slit of the remaining release film can promptly protrude outward from between the attachment site and said adhesive layer, the wave pitch of said wave-shaped slit of said release film is 6 mm to 12.5 mm, and the wave height of each said wave-shaped slit of said release film is 4 mm to 8 mm.
