A tube having higher interlayer adhesion realized by the improved materials and structure of a resin tube without compromise in advantageous characteristics of conventional resin tubes. A multilayer resin tube comprising, provided in sequence from an outer layer side, a body layer (14) of thermoplastic resin, and a barrier layer (18) of thermoplastic resin for restricting fuel permeation, characterized in that the barrier layer (18) ha s a sloped structure comprising an adhesive component-rich outer layer and a barrier component-rich inner layer. |
