Abstract

Disclosed is a multilayered structure that includes no less than 8 resin-layers, the resin-layer including a layer A constituted with a resin composition containing a gas barrier resin, and a layer B constituted with a resin composition containing a thermoplastic resin, at least one of the resin compositions included in the layer A and the layer B that are adjacent with each other containing a metal salt, the content of the metal salt being no less than 1 ppm and no greater than 10,000 ppm in terms of metal element equivalent, and an interlayer adhesive force between the layer A and the layer B being no less than 450 g/15 mm. The layer A and the layer B may be alternately laminated. Moreover, the average thickness of single layer of at least one selected from the layer A and the layer B is preferably no less than 0.01 μm and no greater than 10 μm.
