PROBLEM TO BE SOLVED: To provide a laminated structure which finds out a polyamide resin of an adherend having especially excellent interlayer adhesive properties when a polyester adhesive resin indicating excellent adhesive properties to the polyamide resin is used, remarkably improves interlayer peeling resistance in the interface between the polyamide resin and an adhesive resin, is excellent in interlayer peeling resistance between inner and outer layers of a polyester resin and an intermediate layer of the polyamide resin, suppresses yellowing and the increase of haze, and is excellent in hygienic properties, mechanical strength, and gas-barrier properties. SOLUTION: In the multi-layer structure excellent in interlayer peeling resistance, the inner and outer layers of the polyester resin, the intermediate layer of the polyamide resin formed between the inner and outer layers, and an adhesive resin layer of an acid-modified polyester adhesive resin formed on the interface between the inner and outer layers and the intermediate layer are provided, and the polyamide resin has a terminal amino group concentration of at least 30×10<SP>-6</SP>eq/g.
