The molded component is formed by mixing or laminating a barrier resin (A) having a solubility parameter (calculated from the Fedors' equation) of more than 11 and a thermoplastic resin (B) having a solubility parameter (calculated from the Fedors' equation) of not more than 11. The molded component has excellent gasoline barrier properties and also excellent performance in thermal fusion properties and mechanical strength. The fuel container provided with such a molded component is significantly improved with regard to leakage of fuel from the molded component portion. <IMAGE>
