PROBLEM TO BE SOLVED: To provide an adsorptive film hardly generating squeeze-out of an adsorptive layer at a cutting terminal or floating of the adsorptive layer from a display surface when laminating the film after die-stamping process on a display surface such as the liquid crystal and excellent in die-stamping processability.SOLUTION: There is provided an adsorptive film having an adsorptive layer containing a silicone resin as a main component laminated on a substrate film and total thickness of the adsorptive film of 55 to 225 μm and rupture stress by a tensile test of the substrate film of 75 to 180 N/mm. 【課題】打ち抜き加工後のフィルムを液晶等のディスプレイ表面に貼り付けた場合、切断端部で吸着層のはみ出しが生じたり、ディスプレイ表面からの吸着層の浮きが発生したりすることのない、打ち抜き加工性に優れた吸着フィルムを提供する。【解決手段】基材フィルム上に、シリコーン樹脂を主成分とする吸着層を積層した吸着フィルムにおいて、前記吸着フィルムの総厚みが５５〜２２５μｍであり、かつ前記吸着フィルムの引張試験による破断応力が７５〜１８０Ｎ／ｍｍ２であることを特徴とする吸着フィルム。【選択図】 なし
