Abstract: In the present invention, without decreasing measurement accuracy, a biological component information measurement device can have a miniaturized device structure. In a biological component information measurement device (100), a sample container (104) accommodates a measurement target (105) such as blood, cultured cells, or urine, and a light from a light source (101) is separated into spectral components using a rotating diffraction grating (110) and caused to be incident on the measurement target (105). Due to this configuration, it is possible to reduce the number of parts of a spectral optical system and the amount of space required therefor. As a result, it is possible to, in particular, miniaturize the spectral optical system without decreasing measurement accuracy.
