Abstract: An endoscope includes an insertion section to be inserted from a distal end into a subject. The endoscope further includes a bendable bend portion disposed between the distal end and a proximal end of the insertion section, an actively bent region which is disposed in the bend portion and which is to be bent in accordance with operator's operation, and a passively bent region which is disposed in the bend portion and which is to be bent on receiving an external force.
