Zusammenfassung:	To provide a laminate with excellent gas barrier property and a package using the laminate.SOLUTION: A laminate has a layer A on at least one side of a substrate film, the layer A contains at least aluminum (Al) and oxygen (O), and when an area of 5.0 to 25.0%, an area of 25.0 to 75.0%, and an area of 75.0 to 95.0% are defined as X-part, Y-part and Z-part respectively on the length reference in a depth direction on the layer A, an average composition ratio (O/Al)Z of aluminum (Al) and oxygen (O) in the Z-part and an average composition ratio (O/Al)Y in the Y-part fulfill (1) and (2) below. (1) (O/Al)Z≤2.0. (2) (O/Al)Y/(O/Al)Z≤1.2.SELECTED DRAWING: None 【課題】ガスバリア性に優れた積層体およびそれを用いた包装体を提供する。【解決手段】基材フィルムの少なくとも一方の側にＡ層を有し、前記Ａ層は少なくともアルミニウム（Ａｌ）と酸素（Ｏ）を含み、Ａ層中の深さ方向において、長さ基準５．０～２５．０％の箇所をＸ部、２５．０～７５．０％の箇所をＹ部、７５．０～９５．０％の箇所をそれぞれＸ部、Ｙ部、Ｚ部と規定したときに、Ｚ部におけるアルミニウム（Ａｌ）と酸素（Ｏ）の平均組成比率（Ｏ／Ａｌ）Ｚと、Ｙ部における平均組成比率（Ｏ／Ａｌ）Ｙが、下記（１）および（２）を満たす積層体。（１）（Ｏ／Ａｌ）Ｚ≦２．０。（２）（Ｏ／Ａｌ）Ｙ／（Ｏ／Ａｌ）Ｚ≦１．２【選択図】なし
