Zusammenfassung:PROBLEM TO BE SOLVED: To provide a flexible tube for an endoscope, in which an arbitrary area where a plurality of tubular members are superposed, can be made softer and harder than a non-processed state, a desired flexibility change can be easily obtained, and superior characteristics can also be obtained in point of durability.SOLUTION: An area where lubrication processing to reduce friction resistance between both the tubular members 11, 12 is applied to the outer surface of an inner tubular member 11 and to the inner surface of the outer tubular member 12 out of two tubular members 11, 12 which are superposed on each other, and an area where friction processing for increasing friction resistance between both the tubular members is applied, are provided in series.
