The invention is intended to provide an adhesive patch which contains a drug except bisoprolol and which effectively inhibits the occurrence of oozing out or sticking out of the adhesive layer components from the exposed area of the adhesive layer of the adhesive patch during storage as well as the occurrence of oozing out of the drug from the adhesive layer thereby preventing the reduction in drug content. The support, the release liner and the adhesive layer constituting the adhesive patch each are formed to have a rectangular planar shape and the entire adhesive patch are formed to have a rectangular planar shape, and a protrudent part is formed on the support-side surface of the adhesive patch at a corner thereof. In addition, the adhesive patch may be formed to have a middle part and a peripheral part, and the protrudent part may be formed at a corner of the rectangular middle part. Further, between the adjacent at least two protrudent parts, a connecting built-up part may be provided in which the thickness of the adhesive patch is smaller than the thickness of the adhesive patch in the protrudent part. In case where the release liner has a split part, the split part is made so as not to traverse the protrudent part.
