Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adhesive composition excellent in followability even if an adherend surface contains irregularity such as a level difference, and capable of maintaining elasticity even in a high temperature environment.SOLUTION: An adhesive composition at least includes: an acrylic adhesive; and an isocyanate compound as a crosslinking agent. The acrylic adhesive includes an acrylic resin whose mass average molecular weight is within a range of 50-300 thousand. The adhesive composition includes 0.3-0.8 pt.mass of the isocyanate compound in a solid form ratio to 100 pts.mass of the acrylic adhesive. 【課題】被着体表面に段差等の凹凸がある場合であっても追従性に優れ、かつ高温環境下においても弾性を維持できる粘着剤組成物を提供する。【解決手段】アクリル系粘着剤と、架橋剤としてイソシアネート化合物と、を少なくとも含んでなり、前記アクリル系粘着剤が、質量平均分子量が５〜３０万の範囲にあるアクリル系樹脂からなり、前記イソシアネート化合物が、前記アクリル系粘着剤１００質量部に対して固形比で０．３〜０．８質量部含まれてなることを特徴とする。【選択図】なし
