A microscope stage capable of always heating the entire culture vessel even when the culture vessel is moved in two-dimensional directions, and allowing an object lens and a condenser even in a high-power microscope to approach an object of observation such as a cell until they come into focus. A heating unit (58) faces a well plate (37) on a drive base (49) even when the drive base (49) is driven to any position in two-dimensional directions. Therefore, all the cells A in the small compartments (45) of the well plate (37) are always heated. Since the microscope stage (25) is constituted such that a lower-side base (71) houses an upper-side base (73) and a fixed base (47) in recessed portions, its thickness is considerably small. Accordingly, an object lens (5) and a condenser (3) can approach close to the cells A. Therefore, it is possible for high-power object lens (5) and condenser (3) to focus on the cells A. |
