PROBLEM TO BE SOLVED: To provide an autoanalyzer with which it is possible to adjust the temperatures of a plurality of portions that require temperature adjustment with a smaller amount of power consumption as a whole.
SOLUTION: The autoanalyzer comprises: an air conditioning space 20 which is separated from the surrounding and in which a reagent is used; a Peltier unit 1 having a Peltier element 101 for adjusting the air temperature of the air conditioning space 20; a heat sink 111 for cooling or heating the Peltier unit 1 by a coolant; a first radiator 12 for heat-exchanging, with the atmospheric air, the coolant having been heat-exchanged with the heat sink 111; pumps 10, 11 for circulating the coolant; a reagent storage unit 30 for cold-storing the reagent; Peltier units 2, 3, 4 having Peltier elements 102, 103, 104 for adjusting the temperature of the reagent storage unit 30; heat sinks 112, 113, 114 for cooling or heating the Peltier elements 102, 103, 104; and a second radiator 13 for releasing the heat of the coolant having been heat-exchanged with the heat sinks 112, 113, 114.
