An endoscope has a first bending portion and a second bending portion. The first bending portion is the distal portion of an elongated insertion member and bent in four directions substantially perpendicular to the longitudinal axis of the insertion member. The second bending portion is bent in at least two directions substantially perpendicular to the longitudinal axis of the insertion member. The endoscope further includes a hand-held unit having a control section that is used to bend the first bending portion and second bending portion. The control section of the handheld unit has an angling knob that is used to bend the first bending portion, and a second angling lever that is used to bend the second bending portion.
