Abstract: PROBLEM TO BE SOLVED: To simplify and miniaturize the whole constitution easily by providing a luminous reagent storage part and a micro light quantity detector in proximity to each other and using a cooling mechanism for luminous reagent as cooling mechanism for the micro light quantity detector, too. SOLUTION: When a cooling plate 33 is cooled by a cooling mechanism, since luminous reagent containers 21, 23 in a storage part 19 are placed on a horizontal part 33H of the cooling plate 33, reagent in the containers 21, 23 can be cooled to a desired low temperature by heat conduction so as to be able to prevent the degradation of the reagent. Since the horizontal part 33H of the cooling plate 33 constitutes the top part of a heat insulating case 31 with a micro light quantity detector 29 enclosed therein, the interior of the heat insulating case 31 is cooled, and as a result, the micro light quantity detector 29 is cooled.
