PROBLEM TO BE SOLVED: To provide a blow-molded article, especially a fuel container, which is excellent in balance among ESCR (environmental stress cracking resistance), impact resistance, and rigidity and in gas-barrier properties. SOLUTION: The blow-molded article is composed of the outermost layer of an ethylene polymer (A) comprising 0.01-1 g/10 min in MFR, 0.910-0.940 g/cm<SP>3</SP>in density, and 200-600 MPa in Olsen flexural rigidity, the innermost layer of an ethylene polymer (B) comprising 0.01-1 g/10 min in MFR, 0.940-0.960 g/cm<SP>3</SP>in density, and 600-1,300 MPa in Olsen flexural rigidity, a barrier layer, an adhesive layer, and a burr recovery layer. In terms of the layer composition ratios, the outermost layer is 10-30%, the innermost layer is 30-50%, the barrier layer is 1-15%, the adhesive layer is 1-15%, and the burr recovery layer is 30-50% (the total of these layer ratios is 100%).
