ABSTRACT:
A composite hose is provided with a corrugated metal tube of an inner layer and rubber filler which is filled in valley gaps between corrugation hills on an outer peripheral side of the corrugated metal tube. A tubular hard resin layer is further provided as cover layer on an outer side of the corrugated metal tube in order to enclose the rubber filler within the valley gaps to prevent the rubber filler from escaping radially outwardly.
