Disclosed is a transdermal preparation which is capable of maintaining adhesive properties for a long time even in cases when a crosslinked adhesive, which is capable of containing a sufficient amount of a medical agent, is used for an adhesive layer. Specifically disclosed is a transdermal preparation which is characterized in that one surface of a supporting body is provided with an adhesive layer that contains at least an adhesive and that the adhesive contains two kinds of acrylic resins Acr-A and Acr-B which are obtained by copolymerizing a combination of specific monomers.本發明的課題在於提供一種經皮吸收型製劑，該經皮吸收型製劑，在黏著劑層中使用能夠含有充分量的藥劑之交聯型黏著劑，且能夠長時間維持黏貼性。本發明的經皮吸收型製劑，其在支撐體的單面上至少具備含有黏著劑的黏著劑層，其特徵在於：作為前述黏著劑，含有組合特定單體並使其共聚合而獲得的2種丙烯酸系樹脂Acr-A及Acr-B。
