PROBLEM TO BE SOLVED: To provide an endoscope flexible tube having a surface having no recesses and projections on the connection surface part surface of an insertion tube.SOLUTION: For an endoscope flexible tube, a bend part 13 is attached to the distal end side of a flexible part 12 in the structure of the endoscope flexible tube. The endoscope flexible tube includes: an annular connection tube 30 for connecting the bend part 13 and the flexible part 12 an annular outer cover 29 provided coaxially and adjacently to the connection tube 30 and an annular first fixing member 46 fitted to an outer peripheral surface over the connection tube 30 and the outer cover 29. On the connection tube, a projection 30D is formed. The projection 30D has an outer diameter corresponding to the inner diameter of the inner wall surface of the first fixing member 46. By abutting the projection 30D on the inner wall surface of the first fixing member 46, the first fixing member 46 and the connection tube 30 are turned into a coaxial positional relationship.
