To provide a film for a plaster support medium which has medicine barrier property and extensibility, and furthermore is equipped with an effect of preventing peel from skin when applied on skin as a plaster.SOLUTION: A film for a plaster support medium has a resin layer having medicine barrier property, the thickness of the resin layer is 5 μm or more and 150 μm or less, the resin layer is bent in a thickness direction at least at a part thereof, an uneven structure on which a recess and a protrusion are repeated along a surface is provided, and a difference in height between the recess and the protrusion is larger than the thickness of the resin layer. In the uneven structure, the top part of the protrusion and the bottom part of the recess, which are adjacent to each other, are connected by a wall part, the film includes an outer peripheral portion including a planned cutting position within a plane, the height of the highest point in a thickness direction of the outer peripheral portion is lower than the highest point in a thickness direction of an area other than the outer peripheral portion.SELECTED DRAWING: Figure 2 【課題】薬剤バリア性と伸び性を有し、さらに貼付剤として皮膚に貼り付けた際の皮膚からの剥がれを防ぐ効果を備えた貼付剤支持体用フィルムを提供する。【解決手段】貼付剤支持体用フィルムは、薬剤バリア性を有する樹脂層を有し、樹脂層の膜厚は５μｍ以上１５０μｍ以下であり、樹脂層は、少なくとも一部において厚さ方向に屈曲され、面に沿って凹部と凸部を繰り返す凹凸構造が設けられており、凹部と凸部との高低差が樹脂層の膜厚よりも大きく、凹凸構造は、隣り合う凸部の頂部と凹部の底部とが壁部によって連結されており、面内における切断予定位置を包含する外周部分を備え、外周部分における厚さ方向で最も高い箇所の高さは、外周部分以外における厚さ方向で最も高い箇所よりも低い。【選択図】図２
