Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adhesive composition capable of forming a laminate capable of keeping an adhesive strength at high level even when immersed in an electrolyte solution of 85°C for 2 weeks or more in the case of aging at 40°C for approximately 3 days; and to provide a packaging material for a power storage device, a container for a power storage device and a power storage device which are more excellent in electrolyte resistance than the prior arts.SOLUTION: An adhesive composition contains a polyolefin resin (A) having a carboxyl group or an acid anhydride group, and an epoxy compound (B) obtained by reaction of a polymer (B1) of an unsaturated fatty acid and a compound (B2) having two or more epoxy groups.SELECTED DRAWING: None 【課題】４０℃、３日間程度のエージングの場合に、８５℃の電解質溶液に２週間以上浸漬されても接着強度を高レベルで維持できる積層体を形成できる接着剤組成物の提供。従来よりも電解質耐性に優れる蓄電デバイス用包装材、蓄電デバイス用容器および蓄電デバイスの提供。【解決手段】本発明は、カルボキシル基もしくは酸無水物基を有するポリオレフィン樹脂（Ａ）と、不飽和脂肪酸の重合体（Ｂ１）と２つ以上のエポキシ基を有する化合物（Ｂ２）との反応により得られるエポキシ化合物（Ｂ）とを含有することを特徴とする接着剤組成物。【選択図】なし
