A multilayered stretch-blow-molded container obtained by biaxially stretch-blow-molding a multilayered preform that includes inner and outer layers of an ethylene terephthalate polyester resin, and at least one intermediate layer of a lowly crystallizable ethylene terephthalate polyester resin and a gas-barrier aromatic polyamide resin. A difference of refractive index (ΔRI) between the lowly crystallizable ethylene terephthalate polyester resin and the gas-barrier aromatic polyamide resin is represented by formula (1), n ΔRI=|RI E −RI A | (1)n n is not more than 0.03, wherein RI E and RI A are refractive indices of injection-molded plates made, respectively, from the lowly crystallizable ethylene terephthalate polyester resin and the aromatic polyamide resin after they have been biaxially stretched into 3×3 times simultaneously, and the haze in the body portion is not more than 3%. |
