The automatic analyzer includes: a sample dispensing unit that dispenses a sample into a reaction vessel; a reagent dispensing unit that dispenses a reagent into the reaction vessel; a control unit that controls the sample dispensing unit and the reagent dispensing unit; and a measurement unit that measures a mixed solution of the sample and the reagent mixed in the reaction vessel. The reagent includes three types of reagents of: a first reagent that specifically binds to an antigen in the sample; a second reagent that specifically binds to a site different from that to which the first reagent binds with respect to the antigen and has a label to be detected by the measurement unit; and a third reagent that specifically binds to a site different from the binding site of the first reagent and the antigen and contains insoluble carriers.
