Abstract
A flexible tubeis constituted of a flexible tube materialand a covering layerof two-layers of constitution having an inner layerwhich covers the entire peripheral surface of the flexible tube materialand an outer layerwhich covers the entire peripheral surface of the inner layer. The covering layeris two-layer molded to have the inner layerand the outer layer, by supplying two kinds of resins into one molding die at the same time, with being overlapped each other. As resins for molding the inner layerand the outer layer, a combination of the soft resin and the hard resin is selected to be in conditions that the difference at the 100% modulus value, which is an index of a hardness after molding, is equal to or more than 10 MPa, and that the difference of the melt viscosity in the molding temperature of 150° C. to 200° C., which is an index of the fluidity in the molten state, is equal to or less than 2500 PaS.
