PROBLEM TO BE SOLVED: To provide a flexible tube for an endoscope having the original flexibility of the flexible tube and having excellent durability preventing the generation of wrinkles in the outer skin of the flexible tube. SOLUTION: In the flexible tube for the endoscope having a spiral tube 80 formed by spirally winding a strip-like sheet, a reticulated tube 84 for covering the outer peripheral surface of the spiral tube 80 and the resin outer skin 86 covering the outer peripheral surface of the reticulated tube 84, a resin inner skin 82 is interposed between the spiral tube 80 and the reticulated tube 84 without being joined to the spiral tube 80 and the outer skin 86 is joined to the outer peripheral surface of the inner skin 82 through the resin adhesive 94 selectively applied to the gap P of the reticulated tube 84.
