Summary:PROBLEM TO BE SOLVED: To provide an adhesive sheet having further improved drop resistance, with good repulsion resistance being maintained.SOLUTION: An adhesive sheet includes an adhesive layer mainly composed of an acrylic polymer. The acrylic polymer includes a polar group-containing monomer as the constituent monomer component in a content of 15 wt.% or more relative to the whole monomer components to constitute the acrylic polymer. The polar group-containing monomer further includes a nitrogen atom-containing monomer in a content of 40 wt.% or more. The adhesive layer is formed of an adhesive composition including an acrylic polymer component and an acrylic oligomer.SELECTED DRAWING: None 【課題】良好な耐反撥性を維持しつつ、耐落下衝撃性がさらに改善された粘着シートを提供する。【解決手段】アクリル系重合物を主成分として含む粘着剤層を備える粘着シートが提供される。前記アクリル系重合物は、その構成モノマー成分として極性基含有モノマーを含む。また、前記極性基含有モノマーは、前記アクリル系重合物を構成する全モノマー成分のうち１５重量％以上の割合で含まれている。さらに、前記極性基含有モノマーは、窒素原子含有モノマーを４０重量％以上の割合で含む。そして、前記粘着剤層は、アクリル系重合成分とアクリル系オリゴマーとを含む粘着剤組成物を用いて形成されたものである。【選択図】なし
