An operation microscope includes: an ordinary light path that guides light from an observation target to an eyepiece a first secondary light path branched off from the ordinary light path a second secondary light path merging with the ordinary light path an imaging unit that images the observation target using light from the first secondary path a display unit that displays an image based on an image signal from the imaging unit toward the second secondary path and a reflector provided at a branch point of the ordinary light path and the first secondary light path in such a manner as to be capable of pulling off the branch point, and that bends the ordinary light path by reflection. The first secondary light path extends from the branch point along an extension of the ordinary light path before being reflected.
