A multilayer container having a layer configuration of 3 or more layers including, as layered in that order from an inner layer to an outer layer, an oxygen-permeable layer (A) containing an oxygen-permeable resin as the main component thereof, an oxygen-absorbing adhesive layer (B) containing, as the main components thereof, an oxygen-absorbing resin composition (b1) containing a deoxidant composition (b1-i) and a thermoplastic resin (b1-ii) and an adhesive resin (b2), and a gas-barrier layer (C) containing a gas-barrier resin as the main component thereof, wherein the gas-barrier resin is a polyamide resin (X) including a diamine unit containing a metaxylylenediamine unit in an amount of 70 mol% or more and a dicarboxylic acid unit containing 75 to 96 mol% of an ±,É-linear aliphatic dicarboxylic acid unit having 4 to 20 carbon atoms and 25 to 4 mol% of an aromatic dicarboxylic acid unit, the content of the deoxidant composition (bl-i) in the oxygen-absorbing adhesive layer (B) is 5 to 50% by mass relative to 100% by mass of the material constituting the oxygen-absorbing adhesive layer (B), the content of the adhesive resin (b2) is 20 to 70% by mass relative to 100% by mass of the material constituting the oxygen-absorbing adhesive layer (B), and the thickness of the oxygen-absorbing adhesive layer (B) is 10 to 30% of the total thickness of the multilayer container. |
