The purpose of the present invention is to provide an endoscope in which an observation field-of-view can be easily changed using one operation member, and which performs display such that display image up-down and left-right directions and an observation direction always match, even if the observation field-of-view is changed. To achieve the foregoing, provided is an endoscope comprising: an image pickup unit 20 which includes an image pickup element 21 an optical axis bending optical system for guiding light rays from a subject towards the image pickup unit an operation input means 3 which is oscillatable an operation conversion means 25 which resolves the input of the operation input means and generates a plurality of outputs and an operation transmission means which transmits the output of the operation conversion means to a plurality of moveable units. The optical axis bending optical system includes: a first prism 11 which is supported so as to freely rotate about a second optical axis O2 and a second prism 12 which is supported so as to freely rotate about a third optical axis O3. The operation transmission means includes: an image pickup linking means 22 which rotatably supports the image pickup unit 20 and a prism rotation transmission means comprising a first transmission member 23 for rotating the first prism about the second optical axis and a second transmission member 24 for rotating the second prism, integrally with the first prism, about a third optical axis.La présente invention a pour objet de fournir un endoscope pour lequel un champ de vision dobservation peut être facilement modifié à laide dun seul élément dactionnement et qui effectue un affichage de telle sorte que les directions haut et bas et gauche et droite de limage daffichage et une direction dobservation correspondent toujours, même si le champ de vision dobservation est modifié. Pour obtenir ce qui précède, linvention concerne un endoscope comprenant : une unité de capture dimage (20)
