Abstract

An automatic analyzer which accurately detects a liquid volume of a reagent irrespective of a shape of a reagent container is provided. The invention is directed to an automatic analyzer including: a reagent container that contains a reagent; an emission unit that is provided outside the reagent container and emits light so as to pass inside the reagent container; a light receiving unit that is provided outside the reagent container and receives the light emitted from the emission unit; and a determination unit that, based on the light received by the light receiving unit, detects a liquid level inside the reagent container, and determines whether a liquid volume in the reagent container becomes equal to or less than a predetermined value from the liquid level. A wavelength of the light is determined based on a material of the reagent container and a type of the reagent.
