Summary:To provide an adhesive sheet having good workability, the adhesive sheet as a whole having reduced dependency on fossil resources.SOLUTION: This adhesive sheet is provided with a substrate layer containing a polyester resin and an adhesive layer disposed on at least one surface of the substrate layer. At least 50% of the total carbon contained in the adhesive layer is biomass-derived carbon. Moreover, the polyester resin contains biomass-derived carbon.SELECTED DRAWING: Figure 3 【課題】粘着シート全体として化石資源材料への依存度を低減することができ、かつ良好な加工性を有する粘着シートを提供すること。【解決手段】ポリエステル樹脂を含む基材層と、該基材層の少なくとも一方の面に配置された粘着剤層と、を備えた粘着シートが提供される。前記粘着剤層に含まれる全炭素の５０％以上はバイオマス由来炭素である。また、前記ポリエステル樹脂はバイオマス由来炭素を含む。【選択図】図３
