Abstract

An object of the invention is to provide an automatic analyzer that reduces carryover between liquids and achieves high dispensing accuracy. The automatic analyzer includes: a dispensing mechanism configured to dispense a sample contained in a sample container or a reagent contained in a reagent container into a reaction container by operation of a syringe coupled to a nozzle; and a control unit configured to control the dispensing mechanism, in which the automatic analyzer performs a discharge operation in which the control unit operates the syringe in a discharge direction after the dispensing mechanism aspirates the sample or the reagent and before the dispensing mechanism discharges the sample or the reagent to the reaction container, the discharge operation includes a first discharge operation performed in a state where the nozzle is at a position of the sample container or the reagent container, and a second discharge operation performed while the nozzle is moving from the position of the sample container or the reagent container to a position of the reaction container, and an operation amount of the syringe in the first discharge operation is smaller than an operation amount of the syringe in the second discharge operation.
