Abstract
(EN)
An endoscope (1) comprises: an insertion part (10) including a distal end part (11) in which an image sensor (11A) that outputs an imaging signal and a laser diode (11B) that converts the imaging signal to an optical signal are disposed, a curve part (12) which changes the direction of the distal end part (11), and a flexible soft part (13) which extends from the curve part (12); an operational part (20) which is disposed on a base end part side of the insertion part (10); a universal cord (30) which extends from the operational part (20); a connector (40) which is disposed on a base end part side of the universal cord (30); an optical fiber (50) which transmits the optical signal inserted through the insertion part; and a stress relaxation part (51) which changes an effective length (L1) which is the length along an insertion direction of the optical fiber (50) according to the stress applied to the optical fiber (50).
