A multilayered container obtained by heat-forming a multilayered sheet or a multilayered preform that includes inner and outer layers of an ethylene terephthalate type polyester resin, and at least one intermediate layer of at least a lowly crystalline ethylene terephthalate type polyester resin and a gas-barrier aromatic polyamide resin, wherein a difference of refractive index (ΔRI) between the lowly crystalline ethylene terephthalate type polyester resin and the gas-barrier aromatic polyamide resin represented by the following formula (1), n ΔRI=|RI E −RI A | (1)n n wherein RI E and RI A are refractive indexes of injection-formed plates made, respectively, from the lowly crystalline ethylene terephthalate type polyester resin and the gas-barrier aromatic polyamide resin after they have been monoaxially stretched into 3 times, is not more than 0.03, and a haze in a side surface of the container is not more than 5%. |
