The present invention relates to a setting method for an image capture area on the occasion of evaluation of a circuit pattern using a scanning charged particle microscope. A circuit pattern that is to be evaluated using an actual image or design data is determined, a plurality of image capture areas are set such that the circuit pattern to be evaluated is included in a section of the field of vision, and images are captured of the plurality of image capture areas. When setting the image capture areas, a permissible value for the distance between adjacent first and second images is set, and the positions of the image capture areas are optimized so as to correspond as closely as possible with the permissible value for distance. As a result, it is possible to improve the throughput of image capture of wide inspection areas that do not fit in the field of vision of the scanning charge particle microscope, and to efficiently carry out determination of an inspection area that may cause electrical failure.
