Abstract: This invention provides an analyzer for judging whether or not a tangible component is present in a sample in a preparation, and analyzing, if a tangible component is present, the tangible component with efficiency and high accuracy. For this purpose, an analyzer (100) of the present invention analyzes a tangible component in a sample (23) held by a preparation (20). The analyzer (100) checks whether or not a tangible component is present in the sample (23) by extensively observing an area in a certain visual field in which area the tangible component is assumed to be present. If the tangible component is judged to be present, the analyzer (100) analyzes the tangible component. Then, another visual field is selected, and another analysis is started therein so as to analyze only in the vicinity of the area where the tangible component was judged to be present.
