PROBLEM TO BE SOLVED: To simplify an insertion part, to perform easy assembly work, to improve insertability and to promote ruggedization. SOLUTION: A traction wire 42 for curving a curve part 9 in linkage with an operation from an endoscope operation part 3 is inserted into an endoscope insertion part 2 where a freely curvable curve part 9 is connected and arranged, and a connection pipe 54 provided with a wire guide 20 for guiding the traction wire 42 is disposed at the connection part of the proximal end of the curve part 9 and the hard part 10 of the endoscope insertion part 2.
