AUTOMATED ANALYSIS DEVICE

To provide an automatic analyzer having a reagent carrying mechanism capable of reducing a burden on an operator, which can reduce degradation in throughput of the device and an installation area to be smaller compared to the related art. The automatic analyzer includes a plurality of reagent dispensing mechanisms 7, 8, 9, and 10 that dispense a reagent from a reagent bottle 12 into a reaction container 2; a plurality of reagent disks 11A and 11B that store the reagent bottles 12; reagent carrying-in positions 31A and 31B provided in the respective reagent disks 11A and 11B to put in the reagent bottles 12 to the respective reagent disks 11A and 11B; and a carrying mechanism that carries the reagent bottles 12 between the respective reagent carrying-in positions 31A and 31B and a reagent bottle gripping position 43a, in which when an automatic analyzer 100 is viewed from a vertically upper side, the reagent bottle gripping position 43a is positioned between the reagent carrying-in positions 31A and 31B on a device front side of the automatic analyzer 100.
