Zusammenfassung:	To provide an adhesive containing a polyester-based polymer synthesized using a biomass material, the adhesive having high shear adhesive force.SOLUTION: The present invention provides an adhesive composition containing a polyester-based polymer in which 50% or more of the constituent carbon is biomass-derived carbon. The adhesive composition further contains a tackifier resin and a crosslinking agent. The polyester-based polymer contains an aromatic ring, the tackifier resin also contains an aromatic ring, but the crosslinking agent does not contain an aromatic ring.SELECTED DRAWING: Figure 1 【課題】バイオマス材料を用いて合成されたポリエステル系ポリマーを含む粘着剤において、高いせん断接着力を得ること。【解決手段】構成炭素の５０％以上がバイオマス由来炭素であるポリエステル系ポリマーを含む粘着剤組成物が提供される。この粘着剤組成物は、粘着付与樹脂および架橋剤をさらに含む。そして、前記ポリエステル系ポリマーは芳香環を含み、前記粘着付与樹脂も芳香環を含み、前記架橋剤は芳香環を含まない。【選択図】図１
