PROBLEM TO BE SOLVED: To provide an endoscope provided with high sealability while reducing manufacturing costs, the endoscope also achieving a reduced diameter thereof .SOLUTION: In an endoscope that comprises a camera unit 3 provided at a leading end of an insertion unit to be inserted into an observation object, the camera unit comprises: an imaging unit 4 that has an imaging element optical elements 34 to 38 that form an optical image on an imaging surface of the imaging element a lens barrel 5 that holds the optical elements a cover member 6 that covers a front side of the optical elements and a cylindrical frame member 21 that stores the lens barrel inside and holds the cover member and the imaging unit at the front and back thereof. The cover member is fitted in an open section 51 on a front side of the cylindrical frame member and is fixed to the cylindrical frame member while being sealed with an adhesive. The imaging unit is arranged at an open section 52 on a rear side of the cylindrical frame member and is fixed to the cylindrical frame member while being sealed with the adhesive.COPYRIGHT: (C)2015,JPO&INPIT【課題】製造コストを抑えつつ高い密閉性を確保するとともに小径化を図ることができるようにする。【解決手段】観察対象の内部に挿入される挿入部の先端にカメラ部3を備えた内視鏡において、カメラ部が、撮像素子を有する撮像部4と、撮像素子の撮像面に光像を結像させる光学素子34~38と、この光学素子を保持する鏡筒5と、光学素子の前面側を覆うカバー部材6と、鏡筒を内部に収容するとともに、カバー部材および撮像部を前後に保持する筒状フレーム部材21と、を備え、カバー部材が、筒状フレーム部材における前側の開放部51に嵌め込まれて、筒状フレーム部材に対して接着剤により密閉状態で固定され、撮像部が、筒状フレーム部材における後側の開放部52に配置されて、筒状フレーム部材に対して接着剤により密閉状態で固定されるものとする。【選択図】図3
