An endoscope having a proximal end, a distal end, a handle, and an insertion tube that terminates in a tip section. The tip section includes a bending section and an articulated tip part, and the bending section includes articulated segments, each articulated segment including a guide passage for a control member. The proximal end of the elongated control member is attached to an operating member arranged at the handle and the distal end of the elongated control member is attached to the most distal articulated segment of the bending section. An intermediate section of the elongated control member passes through said guide passages. The intermediate section has a reduced overall cross-sectional area as compared to the majority of said elongated control member.
