Abstract

In the multilayer bottle of the present invention, an outermost layer and an innermost layer are each composed of a polyester (Z1); a barrier layer is composed of a resin composition containing 40 to 99 parts by mass of a polyamide (X) and 1 to 60 parts by mass of a polyester (Z2); an alkali compound (A) is blended in the resin composition; and furthermore, the resin composition satisfies the following formulae (1) to (3).0.01≤≤6.5  (1)3.2≤≤73.1  (2)≥29.2−0.218α  (3)In the formulae, P represents a molar concentration (μmol/g) of phosphorus atoms; M represents a molar concentration (μmol/g) of alkali (earth) metal atoms; and α represents the parts by mass of the polyamide (X) contained in the resin composition.
