PROBLEM TO BE SOLVED: To provide a surgical microscope which allows a 3D camera to be attached thereto without sticking out upward.SOLUTION: As a 3D camera accommodating room 21 is provided to accommodate a 3D camera 22, the 3D camera 22 is accommodated in the 3D camera accommodating room 21 for the most part and, as such, does not stick out upward from a surgical microscope 1. When the 3D camera 22 is not used, the 3D camera accommodating room 21 is covered with a cap 23, which prevents dust and foreign matter from entering the 3D camera accommodating room 21.SELECTED DRAWING: Figure 1
