An endoscope includes an insertion section including a first bending portion and a second bending portion provided on a proximal end side of the first bending portion, a first bending drive mechanism and a second bending drive mechanism. The first bending drive mechanism includes a first traction member passing inside the second bending portion and being able to cause the first bending portion to bend, and an operation input portion to receive an operation input to cause the first bending portion to bend. The second bending drive mechanism acts in response to an operation input to the operation input portion, and includes at least one set of second traction members separated from the first traction member by distances almost equal to each other in a circumferential direction of the second bending portion to apply a compressive force to the second bending portion when being pulled.
