<p>Provided is an autoanalyzer which is equipped with a reagent disc having a plurality of reagent containers mounted thereon and performs qualitative/quantitative analysis of a living body sample such as blood or urine, wherein measurement error of the liquid level of reagent caused by swinging of the liquid surface incident to rotary operation of the reagent disc is reduced. Assuming a predetermined cycle time is one unit, the reagent disc having the reagent containers mounted thereon is transported to a liquid level detection position using two units or more when the liquid level of the reagent is measured.</p>
