Abstract: A single use endoscope device which is inserted inside a subject includes: a distal end portion which includes at least an imaging element; an operation unit which operates an operation of the endoscope device; a curved portion which can be curved inside the subject by operating the operation unit; a fractured portion which detaches the distal end portion from the curved portion; and a soft portion which is extended from the operation unit to the curved portion. The distal end portion, the curved portion and the soft portion are inserted in the subject, the operation unit, the curved portion, and the soft portion are discarded after use of the endoscope device, and the distal end portion and at least the imaging element included in the distal end portion are reused.
