PROBLEM TO BE SOLVED: To provide an endoscope device allowing the reduction of a diameter of an insertion tube while suitably preventing damage or the like of built-in objects inserted through the insertion tube.SOLUTION: In an endoscope device wherein a plurality of built-in objects are inserted through an insertion tube and a bending section, the bending section has: ferrules provided in both ends in the long direction and a plurality of bending members arranged and disposed in the axial direction between the ferrules. A lumen of at least one of the ferrules has a plurality of projections 54A-54D each formed by increasing a thickness of a wall face, and a positioning face 55 having a positioning hole 53 restricting the movement of the built-in objects in a direction orthogonal to the axis of the insertion tube within the insertion tube is formed by the projections. The plurality of built-in objects includes: signal lines 36 connected to an observation means and the other built-in objects. The positioning hole has: a first region through which the signal lines 36 are inserted and a second region through which the other built-in objects are inserted. The signal lines 36 and the other built-in objects are disposed such that they cannot move between the first region and the second region.
