A blow-molded container having a pinch-off part and having, as an innermost layer, a resin composition layer that comprises an ethylene/vinyl alcohol copolymer (A) and a flexible resin (B), characterized in that the flexible resin (B) is a thermoplastic styrene elastomer or an alpha-olefin polymer, the mass ratio of the ethylene/vinyl alcohol copolymer (A) to the flexible resin (B), [(A)/(B)], is in the range of 75/25 to 90/10, and the resin composition layer has a sea-island structure in which the ethylene/vinyl alcohol copolymer (A) is the matrix phase and the flexible resin (B) is the dispersed phase, the dispersed phase having a distance between the particle walls of 0.3 mum or less. |
