摘要

An object of the present invention is to provide an endoscope that can contribute to diameter reduction, and therefore, the endoscope of the present invention has a first window (101) through which light for forming an optical image is transmitted. , A plate-like member having a first light-shielding portion (102) formed on the outer periphery of the first window and a second window (103) formed on the outer peripheral side of the first light-shielding portion and transmitting illumination light. An imaging unit in which a plurality of (104) are coaxially laminated and a plurality of plate-shaped members are fixed, and an optical member (106) is arranged so as to face the first window at the first end of the optical member and an optical image is formed. (110), the illumination unit (111) which is arranged on the outer side of the image pickup unit in the outer peripheral direction so as to face the second window and emits illumination light, and the side of the second end which is opposite to the side of the first end. An optical member having a third window (114) corresponding to the first window and a second light-shielding portion (113) formed on the inner peripheral edge of the third window and corresponding to the first light-shielding portion. A third window and a second light-shielding portion are arranged at positions facing the second end, and a cover member (112A) arranged so as to surround the outer peripheral surface of the optical member is provided.
