A resin tube for fuel piping, satisfying, despite the use of a thermoplastic resin as the material, heat-resistant performance that is required and sufficient even in a high-temperature environment such as in an engine room. A first heat-resistant protective resin layer (12) made of a foaming TPE resin is formed on the outer peripheral surface of a body tube (10) made of a thermoplastic resin, and a second heat-resistant protective resin layer (14) made of a fire- resistant TPE resin is formed in a superposing manner on the first heat- resistant protective resin layer (12).
