Miniaturization, reduce the cost in the United States Patent endoscope. SOLUTION: In the endoscope, lens, which is squeezing 51 is disposed between the lens L2, L3 houses the lenses L1 and L2 as a lens L1 and the rear lens group as the front group lens in the lens support member 39 a unit 35, an imaging device 33 for imaging surface 41 is covered with the element cover glass 43, the adhesive resin for fixing the lens unit 35 and the element cover glass 43 to match the optical axis of the lens to the center of the imaging plane 41 37 When, provided to suppress rough surface portion 73 a total reflection on the outer circumferential surface of the light propagating through the lens L2, L3 are formed on the outer peripheral surface of the lens L2, L3, and.FIELD 4【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、レンズ支持部材39に前群レンズとしてのレンズL1及び後群レンズとしてのレンズL2,L3を収容しレンズL1とレンズL2との間に絞り51が配置されるレンズユニット35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、撮像面41の中心にレンズの光軸を一致させたレンズユニット35と素子カバーガラス43とを固定する接着用樹脂37と、レンズL2,L3の外周面に形成されレンズL2,L3を伝搬する光の外周面での全反射を抑制する粗面部73と、を設けた。【選択図】図4
