PROBLEM TO BE SOLVED: To provide a multilayer body that holds excellent oxygen-absorbing properties and can sufficiently inhibit a bad smell.SOLUTION: A multilayer body contains a seal layer (A) containing thermoplastic resin, an oxygen-absorbing layer (B) containing the thermoplastic resin and iron powder, and an oxygen barrier layer (D) having oxygen barrier properties, which are laminated in this order. At least one of the seal layer (A) and the oxygen barrier layer (D) contains an ionomer as the thermoplastic resin.SELECTED DRAWING: Figure 1 【課題】優れた酸素吸収性を保持すると共に、臭気を十分に抑制することのできる多層体を提供する。【解決手段】熱可塑性樹脂を含有するシール層（Ａ）、熱可塑性樹脂と鉄粉とを含有する酸素吸収層（Ｂ）、並びに、酸素バリア性を有する酸素バリア層（Ｄ）を、この順に積層して備える多層体であって、シール層（Ａ）及び酸素バリア層（Ｄ）の少なくとも一方が、熱可塑性樹脂としてアイオノマーを含有する、多層体。【選択図】 図１
