Provided by the present invention is a multilayered structure in which at least 4 resin-layers constituted with a resin composition containing an ethylene-vinyl alcohol copolymer are contiguously laminated. A single layer of the resin layer has an average thickness of preferably no less than 0.01 µm and no greater than 10 µm. The average thickness is preferably no less than 0.1 µm and no greater than 1,000 µm. When the content of ethylene units of the ethylene-vinyl alcohol copolymer is no less than 3 mol% and no greater than 70 mol%, the saponification degree is preferably no less than 80 mol%.

摘要： An object of the present invention is to provide a vapor-deposited film that enables the formation of a pinhole and/or a crack due to flexure thereof in a processing of the vapor-deposited film such as lamination to be suppressed, and the deterioration of the gas barrier property thereof to be inhibited. The present invention relates to a vapor-deposited film including a substrate film that contains a polyvinyl alcohol polymer, and a metal vapor-deposited layer provided on the substrate film, a mean particle size in the metal vapor-deposited layer as determined using an electron microscope being 150 nm or less. The average thickness of the metal vapor-deposited layer is preferably 30 nm or more and 100 nm or less.
