To provide an imaging apparatus including two optical systems having parallax capable of reducing the size of diameter of an objective optical system.SOLUTION: An endoscope device 1 comprises: two light path forming optical systems 22R, 22 L； an imaging optical system 36； two convex power parts 25R, 25 L each of which has a convex-shaped part, and which are disposed in the two light path forming optical systems 22R, 22 L so as to output outgoing beams from the two light path forming optical systems 22R, 22 L to an imaging optical system 36； and an aperture component 26a having two apertures 26a1, 26a2 for allowing the beam output from the two convex power parts 25R, 25 L to pass therethrough. Two centers CR, CL of the two apertures 26a1, 26a2 are positioned closer to the optical axis O of the imaging optical system 36 with respect to optical axises OR, OL of the two light path forming optical systems 22R, 22 L.SELECTED DRAWING: Figure 2【課題】本発明は、対物光学系の細径化を図ることができる、視差を有する２つの光学系を含む撮像装置を提供する。【解決手段】内視鏡装置１は、２つの光路形成光学系２２Ｒ、２２Ｌと、結像光学系３６と、凸状部を有し、２つの光路形成光学系２２Ｒ、２２Ｌ内に設けられ、２つの光路形成光学系２２Ｒ、２２Ｌからの出射光を結像光学系３６へ向けて出射するように配置された２つの凸パワー部２５Ｒ、２５Ｌと、２つの凸パワー部２５Ｒ、２５Ｌから出射される光を透過する２つの開口２６ａ１、２６ａ２を有する絞り部材２６ａを有する。２つの開口２６ａ１、２６ａ２の２つの中心ＣＲ、ＣＬは、それぞれ２つの光路形成光学系２２Ｒ、２２Ｌの２つ光軸ＯＲ、ＯＬに対して結像光学系３６の光軸Ｏ側に位置する。【選択図】図２
