A charged particle microscope includes an electron gun provided inside a barrel and a stage 20. In the stage 20, a sample holder 30 holding a sample SAM can be installed. The stage 20 includes an annular rough movement stage member 21a and an annular fine movement stage member 21b. An X rough movement actuator 22a and a Y rough movement actuator 23a are connected to the rough movement stage member 21a. An X fine movement actuator 22b and a Y fine movement actuator 23b are connected to the fine movement stage member 21b. Here, a first movable range in which the X rough movement actuator 22a and the Y rough movement actuator 23a are able to move the rough movement stage member 21a is broader than a second movable range in which the X fine movement actuator 22b and the Y fine movement actuator 23b are able to move the fine movement stage member 21b. Accordingly, it is possible to improve performance of the charged particle microscope.
