Publication number: 20210223535Abstract: An endoscope includes a lens, an imaging element, an element cover glass configured to cover an imaging surface of the imaging element, a lighting member, and a light-shielding member disposed between the lens and the lighting member. The lens has a quadrangular outer shape in a direction perpendicular to a direction along a center axis of the lens. The imaging element has a quadrangular outer shape in the direction perpendicular to the direction along the center axis of the lens. The lighting member is disposed outside a side of the lens and extends in the direction along the center axis of the lens. The light-shielding member extends in the direction along the center axis of the lens from an insertion tip surface in a tip portion of the endoscope to the imaging surface of the imaging element. The lens is attached to the element cover glass via an adhesive resin.Type: ApplicationFiled: April 5, 2021Publication date: July 22, 2021Inventors: Yuichi HATASE, Naoyuki HARAGUCHI, Satoru MIYANISHI, Takafumi SANADA
