Abstract

Provided is a component measurement device and a component measurement device set, which are so configured that measurement accuracy is unlikely reduced even if a plurality of light sources is used. A component measurement device according to the present disclosure is a component measurement device for measuring a component of interest in blood on the basis of optical characteristics of a mixture containing a color component produced by a color reaction between the component of interest in the blood and a reagent, the component measurement device including: a first light source configured to emit irradiation light of a first predetermined wavelength to be emitted to the mixture; and a second light source configured to emit irradiation light of a second predetermined wavelength to be emitted to the mixture and to be used for estimation of a noise amount contained in a measured value of absorbance of the mixture measured by using the irradiation light of the first light source, the noise amount being derived other than from the color component, in which the first light source and the second light source are aligned in a flow path width direction perpendicular to a flow direction of the blood at a position where the mixture is present in a flow path of the blood.
