PROBLEM TO BE SOLVED: To provide an endoscope flexible tube having such a constitution that an outer sheath is attached to an outer circumferential surface of a net-like tube formed by braiding a plurality of wire bundles in which metallic wires and nonmetallic wires are juxtaposed, the endoscope flexible tube having excellent durability hardly generating wrinkles and buckling after repeated use. SOLUTION: The net-like tube 12 is formed by braiding the plurality of wire bundles 22. In each of the wire bundles 22, development lengths of non-metallic fiber wires 22b are formed longer than those of metallic wires 22a, consequently the non-metallic fiber wires 22b are in a loosened state with respect to the metallic wires 22a as a whole.
