An endoscope according to exemplary embodiments of the present disclosure includes an insertion section configured to be bendable, extend from a base end to an idle end, and be rotatable about an extension direction thereof, a functional member provided to the idle end, a plurality of control wires, trailing ends of which are fixed to the idle end, and a traction member provided to the base end and configured to tow starting ends of the plurality of control wires so as to bend the insertion section. When the insertion section is rotated, the functional member, the plurality of control wires, and the traction member are rotated along with the insertion section. The traction member maintains a bending direction and a bending angle of the insertion section by changing a traction amount with respect to the plurality of control wires.
