To provide a plaster which shows both of high followability to skin expansion and contraction and to a bended surface and good handling properties in application. A percutaneous absorption preparation comprising a plaster and a release liner, wherein: the plaster comprises a support which contains a woven fabric and/or a nonwoven fabric, an adhesive layer which is formed on one surface of the support and which contains a pharmacologically active substance, and a carrier film which is thermally fused on the surface of the support opposed to the surface having the adhesive layer formed thereon and which is to be released after the preparation is adhered to an affected site the release liner covers at least a part of the adhesive layer of the plaster the carrier film has a bending resistance of 150 mm or lower the support has a thickness of 100-1000 [mu]m and the carrier film has an area equivalent to or narrower than the area of the support.本發明之課題在於提供一種兼顧皮膚伸縮時之追隨性或對彎曲面之追隨性與貼附時之操作性的貼附劑。 一種經皮吸收製劑,其係由貼附劑與剝離襯墊所構成者,並且 上述貼附劑係具備 包含編織布及/或不織布之支持體、 形成於上述支持體之一面上之含有藥理活性物質之黏著劑層、及 熱熔合於上述支持體之與形成有上述黏著劑層之面相反之側之面上並欲在應用於患部後加以剝離之承載膜而成, 上述剝離襯墊係被覆上述貼附劑之黏著劑層之至少一部分而成, 上述承載膜具有150 mm以下之抗彎剛度, 上述支持體具有100 μm至1000 μm之厚度, 上述承載膜係具有與支持體相等或小於其之面積之膜。1‧‧‧經皮吸收製劑2‧‧‧貼附劑3‧‧‧剝離襯墊4‧‧‧黏著劑層5‧‧‧支持體6‧‧‧承載膜
