Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel tube heating time and cooling time of which, when the fuel tube is bent, are shortened.SOLUTION: The fuel tube 10 has an inner layer for forming a fuel passage and an outer layer layered on the outer peripheral side of the inner layer. The outer layer is formed from a first polyamide-based resin material selected from PA11, PA12 or PA1012 and the inner layer is formed from a second polyamide-based resin material of PA612. When the melting point of the first polyamide-based resin material and that of the second polyamide-based resin material are defined respectively as Tm1 and Tm2 and the glass transition temperature of the first polyamide-based resin material and that of the second polyamide-based resin material are defined respectively as Tg1 and Tg2, Tm2-Tm1 is 10-30°C and Tg2-Tg1 is 10°C or higher.
