PROBLEM TO BE SOLVED : To provide a resin hose superior in interlayer adhesion and low permeability of fuel, coolant or the like, and to provide a method of manufacturing the same. SOLUTION : The resin hose includes a tubular fluoride series resin layer 1 and a polyamide-based resin layer 2 on the outer periphery thereof. The outer circumferential surface of the fluoride series resin layer 1 is reformed by atmospheric microwave plasma treatment in a rare gas atmosphere like argon, and the polyamide-based resin layer 2 is directly laminated and molded on the reformed face by melt extrusion molding.
