<p>A monitoring device used as a microscope, a physicochemical device, and a medical appliance capable of rather easily preventing a monitored object from coming out of focus by the thermal deformation of a stage unit on which the monitored object is placed. The stage unit comprises a first stage member on which the monitored object is placed and in which a placement member forming the monitoring surface of the monitored object is installed and a second stage member having a placement part for placing the first stage member thereon and supporting the first stage member. The monitoring surface and the contact surface of the placement part with the first stage member with the second stage member are set approximately on the same horizontal plane.</p> |
