Abstract

Provided is an automatic analyzer in which a lid of a reagent vessel does not hinder the dispensing of the reagent. An automatic analyzer for analyzing a specimen includes a reagent dispensing unit for dispensing a reagent from a reagent bottle in which a plurality of reagent vessels storing reagents used for the analysis of the specimen are arranged in one direction, and a reagent rack in which reagent bottles are stored, in which the reagent rack includes a lid opening unit for opening a lid corresponding to an upward opening of the reagent vessel along an arrangement direction of the reagent vessels, and a lid fixing unit for fixing the lid to the outside of a path in which the reagent dispensing unit is inserted into the opening.
