Problem to be solved.A medical imaging device has a left eye imaging element 472 having a rectangular left eye receiving surface 472a receiving a left eye observation light SIL from an observation position of a subject, and a left eye imaging device 472 for outputting a left eye image signal corresponding to the left eye observation light SIL and an observation part A right eye imaging element 482 having a rectangular right eye receiving surface 482a for receiving a right eye observation light Sir having a parallax for the left eye observation light SIL, and a right eye imaging element 482 for outputting a right eye image signal corresponding to the right eye observation light sir .The left and right eye imaging devices 472 and 482 respectively have short sides of light receiving surfaces 472a and 482a for left and right eyes, respectively, in the direction in which the respective optical axes of the observation light SIL and sir for left and right eyes are aligned, and the long sides of the light receiving surfaces 472a and 482a for left and right eyes are two They are opposed to each other.Diagram【課題】小型化を図ること。【解決手段】医療用撮像装置は、被検体の観察部位からの左目用観察光SILを受光する矩形状の左目用受光面472Aを有し、左目用観察光SILに応じた左目用画像信号を出力する左目用撮像素子472と、観察部位からの観察光であって左目用観察光SILに対して視差のある右目用観察光SIRを受光する矩形状の右目用受光面482Aを有し、右目用観察光SIRに応じた右目用画像信号を出力する右目用撮像素子482とを備える。左,右目用撮像素子472,482は、左,右目用観察光SIL,SIRの各光軸が並ぶ方向に左,右目用受光面472A,482Aの各短辺がそれぞれ沿い、かつ、左,右目用受光面472A,482Aの長辺同士が互いに対向して配設されている。【選択図】図4
