It has a polyester layer containing a thermoplastic polyester resin (X) and a polyamide layer containing a polyamide resin (X), the innermost layer is a polyester layer, and has a polyamide layer as an intermediate layer, the polyamide layer The amide resin (Y) has a constitutional unit derived from a diamine and a constitutional unit derived from a dicarboxylic acid, and 70 mol% or more of the constitutional unit derived from this diamine is a constitutional unit derived from xylylenediamine. More than 70 mol% of the constituent units derived from dicarboxylic acids are constituent units derived from α,ω-linear aliphatic dicarboxylic acids having 4 to 20 carbon atoms, and when the total thickness is 100%, the polyamide layer is formed on the inner surface. It is present from a position of 5 to 35% from, and the thickness of the polyamide layer is 1 to 15%, a multilayer container. |
