A means for observing the shape of a sample itself without deforming the sample is provided. An ionic liquid is held by a sample holding member (for example, a microgrid or a mesh) having an opening, and the sample is floated in the ionic liquid for observation by placing the sample therein. Furthermore, an ionic liquid injection mechanism (ionic liquid introduction mechanism) and / or an electrode is provided in the vicinity of the sample holding member. When a voltage is applied to the electrodes, the sample can be moved and deformed in the ionic liquid, and the movement and deformation can be observed. Further, a vapor deposition apparatus is provided in the vicinity of the sample holding member so that the sample can be put into the ionic liquid while vapor deposition. Further, a microcapillary is provided in the vicinity of the sample holding member so that a liquid sample can be put into the ionic liquid. The sample holding member can be rotated.
