AUTOMATIC ANALYSIS DEVICE

Provided is an automatic analysis device capable of adjusting the temperature of a plurality of portions requiring temperature control with less power consumption as a whole.An automatic analysis device includes; an air-conditioned space 20 which is partitioned from the surroundings and in which a reagent is used; a Peltier unit 1 which includes a Peltier element 101 for adjusting an air temperature of the air-conditioned space 20; a heat sink 111 that cools or heats the Peltier unit 1 with a refrigerant; a first radiator 12 which performs heat exchange between the refrigerant which has exchanged heat with the heat sink 111 and the air in the atmosphere; pumps 10 and 11 that circulate the refrigerant; a reagent storage unit 30 which cools and stores the reagent; Peltier units 2, 3, and 4 which include Peltier elements 102, 103, and 104 which adjust a temperature of the reagent storage unit 30; heat sinks 112, 113, and 114 that cools or heats the Peltier elements 102, 103, and 104; and a second radiator 13 which dissipates the heat of the refrigerant that has exchanged heat with the heat sinks 112, 113, and 114.
