PROBLEM TO BE SOLVED: To provide an electron microscope device in which analysis of spacial configuration is made possible by applying a CT method (computerized tomography method) without segmentizing the test piece and application of the CT method is possible in a general case. SOLUTION: By a two-dimensional relative treatment with a reference picture based on a series of transmission images obtained by inclining the test piece for each certain angle, an identical field of view is selected and cut out, thereby the position shifting is corrected.
