PROBLEM TO BE SOLVED: To provide an endoscope distal end structure which can attain a reduction in a diameter of a distal end portion of an endoscope compared to a conventional structure for leading to a reduction in a diameter of an insertion portion, and an endoscope.SOLUTION: An endoscope distal end structure includes: an objective optical system 43a which is disposed in a distal end portion 31 of an insertion portion 4 of an endoscope 2 and condenses an observation image of a subject a prism 44 which refracts and reflects imaging light converged by the objective optical system 43a a solid state imaging device 47 which is disposed in parallel with an optical axis O of the imaging light in the distal end portion 31 and detects the imaging light reflected by the prism 44 for performing photoelectric conversion a circuit board 48 where the solid state imaging device 47 is mounted and a light guide 52 which transmits illumination light to the subject and is disposed to be adjacent to a side part of the prism 44 in the distal end portion 31 and to have at least a part superposed on a side part of the solid state imaging device 47.COPYRIGHT: (C)2015,JPO&INPIT【課題】 従来の構造に比べ、内視鏡の先端部を細径化でき、挿入部の細径化に繋がる内視鏡先端構造および内視鏡の提供。【解決手段】 内視鏡2の挿入部4の先端部31に配設され、被検体の観察像を集光する対物光学系43aと、対物光学系43aにより集束された撮影光を屈折反射するプリズム44と、先端部31内に撮影光の光軸Oに平行配置され、プリズム44によって反射された撮影光を検出して光電変換する固体撮像素子47と、固体撮像素子47が実装された回路基板48と、被検体への照明光を伝送し、先端部31内において、プリズム44の側部に隣接して固体撮像素子47の側部と少なくとも一部が重畳するように配置されたライトガイド52と、を具備する。【選択図】図6
