To easily and inexpensively manufacture an imaging device with high accuracy in which a reflection optical system including a plurality of reflection optical elements is used for an imaging optical system.SOLUTION: A stereo imaging device 100 comprises a plurality of reflection optical elements (103 to 107 and 109 to 113) and an imaging substrate (108) for receiving light which is reflected by the reflection optical elements sequentially. First reflection optical elements (107, 113) with high optical sensitivity for image formation with respect to an imaging element are structured separately from an optical frame (101). Other second reflection optical elements (103 to 106 and 109 to 112) with low optical sensitivity and less influence on performance are integrated with the optical frame (101 or 102) in advance. Regarding adjustment of an optical system, position attitudes of the first reflection optical elements (107, 113) to the optical frame (101) are adjusted, the final position attitudes are determined and then the first reflection optical elements (107, 113) are fixed to the optical frame at the determined positions.SELECTED DRAWING: Figure 2 【課題】複数の反射光学素子を含む反射光学系を撮影光学系に用いた高精度な撮影装置を簡単安価に製造する。【解決手段】ステレオ撮影装置１００は、複数の反射光学素子（１０３...１０７および１０９...１１３）と、これらで順次、反射された光を受光する撮像基板（１０８）を備える。撮像素子への結像に関して光学敏感度の高い第１の反射光学素子（１０７、１１３）を光学フレーム（１０１）と別体構造とする。その他の光学敏感度が低く、性能に関する影響の小さい第２の反射光学素子（１０３...１０６と１０９...１１２）は、予め光学フレーム（１０１あるいは１０２）と一体化させておく。光学系の調整において、光学フレーム（１０１）に対する第１の反射光学素子（１０７、１１３）の位置姿勢を調整し、最終の位置姿勢を決定し、その位置で第１の反射光学素子（１０７、１１３）を光学フレームに固着する。【選択図】図２
