Abstract: The disclosed device, which, using an electron microscope or the like, minutely observes defects detected by an optical appearance-inspecting device or an optical defect-inspecting device, can reliably insert a defect to be observed into the field of an electron microscope or the like, and can be a device of a smaller scale. The electron microscope, which observes defects detected by an optical appearance-inspecting device or by an optical defect-inspecting device, has a configuration wherein an optical microscope that re-detects defects is incorporated, and a spatial filter and a distribution polarization element are inserted at the pupil plane when making dark-field observations using this optical microscope.
