Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus capable of simply and accurately measuring the number of colonies without depending upon naked eyes, excellent in reduction in labor, useful for a sanitary survey of a food, etc., by enabling the measurement of the whole Petri dish and that of an magnified part in the Petri dish. SOLUTION: This apparatus for measuring the number of colonies is constituted so as to arrange a CCD camera 1 at a position to measure the whole Petri dish 4 and a lens 2 for magnifying only a part of the Petri dish 4 between the Petri dish and the CCD camera 1. The apparatus has a driving device 3 for moving the magnifying lens 2 from a space between the CCD camera 1 and the Petri dish 4, if necessary, to enable the measurement of the whole Petri dish and that of an magnified part in the Petri dish.
