A scanning electron microscope of the present invention, when performing the pre-charge of the sample 110, would of the incident electron beams from a plurality of the incident direction 403, 404 relative to the sample, a plurality of rings of a pre-charge area irradiated concentric shape divided into the feature region (807, 813), characterized in that the scanning of the electron beam with respect to the respective ring-shaped area. Thereby, the secondary electrons is lost in the contact hole wall surface is reduced because it is possible to obtain information of the contact hole bottom, the pre-charge during the observation haejyeoseo is charged in the contact hole unevenness by the slope of the electron beam it is difficult to be a problem to resolve in It became.
