Endoscope flexible tube



The purpose of the present invention is to provide an endoscope flexible tube that enables a large internal space to be ensured while maintaining ease of assembly. To achieve this purpose, an endoscope flexible tube according to the present invention includes: a spiral tube (11) formed by spirally winding a belt-like plate; an inner tubular member (14) disposed inside an end (21) of the spiral tube; and an outer tubular member (15) that is disposed outside the end of the spiral tube and holds the end of the spiral tube between itself and the inner tubular member. The inner tubular member has such a configuration that it is disposed inside the end of the spiral tube such that the diameter D1A of the end of the spiral tube is larger than the diameter D1 of a section different from the end of the spiral tube.
