An endoscope includes a first bending portion including a first bending tube which is bendable in multiple directions with respect to a straight state a second bending portion which is provided on a proximal end side of the first bending portion and includes a second bending tube that is bendable in multiple directions with respect to a straight state and also bendable in the same directions as at least two directions of the first bending portion a first bending drive mechanism which is configured to bend the first bending portion in the multiple directions and a second bending drive mechanism. The second bending drive mechanism is configured to interlock with the first bending drive mechanism, is configured to bend the second bending portion in multiple directions when external force is applied to the second bending portion while the first bending portion is straight, and is configured to generate compression force on a bending direction side of the first bending portion with respect to a center axis of the second bending tube in the second bending portion when a bending angle of the first bending portion is increased with respect to the straight state.
