Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adhesive composition which is excellent in foaming resistance against a plurality of types of base materials, does not remarkably rise a haze under high temperature and high humidity environment, and can keep adhesive force.SOLUTION: An adhesive composition contains urethane (meth)acrylate, a monofunctional monomer having a nitrogen atom and an unsaturated bond, and monofunctional (meth)acrylate having a hydroxy group. The urethane (meth)acrylate has a polyether skeleton derived from at least one of polypropylene glycol having a number average molecular weight determined from a hydroxyl value of 5,000-15,000 and polytetramethylene ether glycol having the number average molecular weight of 2,000-5,000, and has a weight average molecular weight of 20,000-300,000.SELECTED DRAWING: None 【課題】複数種の基材に対して耐発泡性に優れると共に、高温高湿環境下においてもヘイズが著しく上昇することなく、かつ粘着力を維持可能な粘着剤組成物を提供する。【解決手段】ウレタン（メタ）アクリレートと、窒素原子及び不飽和結合を有する単官能モノマーと、ヒドロキシ基を有する単官能（メタ）アクリレートとを含有する粘着剤組成物である。前記ウレタン（メタ）アクリレートは、水酸基価から求められる数平均分子量が５０００〜１５０００のポリプロピレングリコール、及び前記数平均分子量が２０００〜５０００のポリテトラメチレンエーテルグリコールの少なくとも一方に由来するポリエーテル骨格を有し、重量平均分子量が２００００〜３０００００である。【選択図】なし
