Zusammenfassung:	To provide a laminate that has high production efficiency and high gas barrier performance despite a simple constitution.SOLUTION: A laminate has a layer A at least on one side of a substrate, and the layer A fulfills conditions 1 and 2. Condition 1: the layer A contains at least one element selected from the group consisting of magnesium, calcium, titanium, zirconium, zinc, and aluminum, and at least one element selected from the group consisting of silicon, stannum, and germanium, and oxygen. Condition 2: a specific relational expression is fulfilled regarding at least any one element of magnesium, calcium, titanium, zirconium, zinc, aluminum included in the layer A. XAinterface/MAinterface>XAwhole/MAwhole, XAinterface, MAinterface: the content ratio of element X (or metal element) in a layer A interface XAwhole, MAwhole: the content ratio of element X (or metal element) in a layer A whole element X: any one of magnesium, calcium, titanium, zirconium, zinc, aluminum.SELECTED DRAWING: None 【課題】生産効率が高くかつシンプルな構成でも高度なガスバリア性を有する積層体を提供する。【解決手段】基材の少なくとも片側にＡ層を有し、Ａ層は条件１及び２を満たす、積層体。条件１：Ａ層はマグネシウム、カルシウム、チタン、ジルコニウム、亜鉛、及びアルミニウムからなる群より選ばれる１種以上の元素、並びに、ケイ素、スズ、及びゲルマニウムからなる群より選ばれる１種以上の元素、及び酸素を含む。条件２：Ａ層に含まれるマグネシウム、カルシウム、チタン、ジルコニウム、亜鉛、アルミニウムの少なくともいずれか１つの元素について、特定の関係式を満たす。ＸＡ界面／ＭＡ界面＞ＸＡ全体／ＭＡ全体ＸＡ界面、ＭＡ界面：Ａ層界面における元素Ｘ（または金属元素）の含有比率ＸＡ全体、ＭＡ全体：Ａ層全体における元素Ｘ（または金属元素）の含有比率元素Ｘ：マグネシウム、カルシウム、チタン、ジルコニウム、亜鉛、アルミニウムのいずれか。【選択図】なし
