  "textContent": "A resin fuel tube is provided, which includes at least one resin layer, wherein the resin layer is made of a resin composition comprising: (A) a polypropylene prepared through polymerization with the use of a metallocene catalyst; and (B) a polypropylene material having a melting point of 137°C to 160°C, the resin composition having a mixing weight ratio of the components (A) and (B) satisfying (A) / (B) = 95/5 to 50/50, wherein the resin layer has a structure such that a soft structural portion (Y) of the component (A) intrudes into a space between crystalline structural portions (X) of the component (B). Therefore, the resin fuel tube is light-weight, excellent in impact resistance and heat resistance, free from fuel leakage, and usable in an atmosphere at 130°C or higher, for example, in an automotive engine room or the like.",
