PROBLEM TO BE SOLVED: To provide a transdermal administration device manufacturing method that can facilitate peeling a filling material comprising a forming material of an administration part from an intaglio plate, and provide a transdermal administration device.SOLUTION: A transdermal administration device manufacturing method comprises an arrangement step of arranging an auxiliary member 20 in a plate material surface 30S by using an intaglio plate 30 having a recess 31 in the plate material surface 30S. A standing part 21 of the auxiliary member 20 extends to a depth direction of the recess 31. An overhanging part 22 is in contact with the plate material surface 30S in each of two or more points equally arranged on a virtual ring surrounding the recess 31 as seen from a direction opposed to the plate material surface 30S, and is overhung from an end of the standing part 21 toward the inside of the ring. Further, the manufacturing method comprises a step of filling the intaglio plate 30 with the forming material of the administration part so as to cover the overhanging part 22, and a step of peeling a filled material Fl comprising the forming material from the intaglio plate 30 by displacing the auxiliary member 20 along the direction of extension of the standing part 21 and separating the overhanging part 22 from the plate material surface 30S.SELECTED DRAWING: Figure 7【課題】投与部の形成材料からなる充填物を凹版から剥離しやすくすることのできる経皮投与デバイスの製造方法、および、経皮投与デバイスを提供する。【解決手段】経皮投与デバイスの製造方法は、凹部３１を版材面３０Ｓに有した凹版３０を用い、版材面３０Ｓに補助部材２０を配置する配置工程を含む。補助部材２０の立設部２１は、凹部３１の深さ方向に延び、張出部２２は、版材面３０Ｓと対向する方向から見て、凹部３１を囲む仮想的な環上に等配された２以上の点の各々で版材面３０Ｓに接し、かつ、立設部２１の端部から上記環の内側に向けて張り出す。さらに、上記製造方法は、投与部の形成材料を、張出部２２を覆うように凹版３０に充填する工程と、補助部材２０を立設部２１の延びる方向に沿って変位させて張出部２２を版材面３０Ｓから離すことによって、形成材料からなる充填物Ｆｌを凹版３０から剥離する工程とを含む。【選択図】図７
