PROBLEM TO BE SOLVED: To provide an adhesive tape or sheet for skin excellent in moisture permeability, having excellent adhesin to a skin surface with reduced skin irritation in detachment from the skin surface.SOLUTION: The adhesive tape or sheet for skin, in the present invention, includes an adhesive layer laminated on at least one side of a substrate. The adhesive layer includes: an acrylic copolymer copolymerized from a monomer mixture including an alkyl (meth)acrylate ester monomer, an alkoxy group-containing ethylenic unsaturated monomer, and a carboxylic group-containing ethylenic unsaturated monomer; and a carboxylate ester; with cross linking treatment. 【課題】皮膚面への良好な貼着性と、皮膚面から剥離除去する際の皮膚刺激を低減することができるとともに、透湿性に優れた皮膚貼着用テープもしくはシートを提供することを課題とする。【解決手段】本発明の皮膚貼着用テープもしくはシートは、基材の少なくとも片面に粘着剤層を積層しており、前記粘着剤層が（メタ）アクリル酸アルキルエステル単量体、アルコキシ基含有エチレン不飽和単量体、カルボキシル基含有エチレン不飽和単量体を含む単量体混合物を共重合してなるアクリル系共重合体と、カルボン酸エステルとを含み、架橋処理が施されている。【選択図】なし
