PURPOSE:To observe efficiently even a thin plate-shaped sample and to prevent bad influences due to temperature by storing a sample stage in a vessel, where a liquid through which ultrasonic waves are transmitted is stored, together with the sample so that they can be immersed in this liquid. CONSTITUTION:A sample stage 17 has a hollow structure, and many through holes 20 are formed on the upper end face as a placing face of a sample 15, and the lower end side is connected to a suction pump 22 through a hollow hose 21 to suck water 19. A vessel 18 is connected to a water circulating pump 24 on the way through a flexible hose 23 to which a temperature control means 25 is inserted. Therefore, when the sample 15 sent to an examination process is placed on the stage 17, the sample 15 is brought closely into contact with the upper end face of the stage 17 and is held plane to be able to execute examination immediately because the pressure in the hollow part side of the stage is negative. Since water 19 in the vessel 18 is held at a certain temperature, examination with a high precision by an ultrasonic microscope can be executed immediately without influences of variance of the water temperature. |
