Abstract: There is provided a multilayer bottle including an outermost layer and an innermost layer which are each made of a thermoplastic polyester resin, and at least one barrier layer interposed between the outermost layer and the innermost layer. The barrier layer contains at least two components including a polyamide obtained by polycondensing a diamine component containing m-xylylenediamine as a main component with a dicarboxylic acid component containing an α,ω-linear aliphatic dicarboxylic acid as a main component, and a thermoplastic resin having a lower molecular weight than that of the polyamide. The multilayer bottle hardly suffers from delamination upon impact or dropping and, therefore, is not required to have a shape with less irregularities or less bends for preventing the delamination, and further has a large freedom of design choice.
