Miniaturization, reduce the cost in the United States Patent endoscope. SOLUTION: In the endoscope, the objective cover glass 91, the image sensor 33 to the imaging surface 41 is covered with the element cover glass 43, a lens 93 interposed between the objective cover glass 91 and the element cover glass 43, imaging lens 93 and the element cover glass 43 to match the optical axis of the lens 93 in the center of the surface 41, and the adhesive resin 37 to fix the objective cover glass 91 and the lens 93, the maximum outer diameter Dmax dicing possible image pickup device 33 It provided a distal portion 15 which is formed in a range of finite diameter ~1.0mm corresponding to the diameter of the circumscribed circle of the substrate, an air layer 95 provided between the lens 93 and the element cover glass 43, a.FIELD 20【課題】内視鏡において小型化、コスト低減を図る。【解決手段】内視鏡において、対物カバーガラス91と、撮像面41が素子カバーガラス43によって覆われる撮像素子33と、対物カバーガラス91と素子カバーガラス43の間に挟まれるレンズ93と、撮像面41の中心にレンズ93の光軸を一致させたレンズ93と素子カバーガラス43、及び対物カバーガラス91とレンズ93を固定する接着用樹脂37と、最大外径Dmaxがダイシング可能な撮像素子33の基板の外接円の直径に相当する有限径~1.0mmの範囲で形成される先端部15と、レンズ93と素子カバーガラス43の間に設けられる空気層95と、を設けた。【選択図】図20
