PROBLEM TO BE SOLVED: To provide a fuel container having excellent fuel barrier properties and stable fuel barrier performance even after receiving a heat shock. An ethylene-vinyl alcohol copolymer containing the following structural unit (1), preferably obtained by copolymerizing 3,4-diacyloxy-1-butene, a vinyl ester monomer, and ethylene. It consists of a laminate in which a thermoplastic resin-containing layer is disposed on both outer layers of an intermediate layer having an ethylene-vinyl alcohol copolymer obtained by saponifying the copolymer. [Chemical 1] (Here, X is a bond chain and is an arbitrary bond chain excluding an ether bond, R1 to R4 are each independently an arbitrary substituent, and n represents 0 or 1.) |
