Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a multilayered molded part for a fuel container excellent in gasoline barrier properties and mechanical strength. SOLUTION: The multilayered molded part for the fuel container consists of a barrier resin composition (A) layer, which consists of 60-95 wt.% of (a1) an ethylene/vinyl alcohol copolymer with an ethylene content of 5-60 mol% and a saponification value of 85% or more and 5-40 wt.% of (a2) a boric acid modified resin, and a resin composition (B) layer, which consists of 1-99 wt.% of at least one kind of a resin (b1) selected from the group consisting of a carboxylic acid modified polyolefin and a boric acid modified resin and 1-99 wt.% of a thermoplastic resin (b2) having a solubility parameter (calculated from formula of Fedors) of 11 or less other than (b1).
