PROBLEM TO BE SOLVED: To provide a biological information measurement device being miniaturized in a device configuration without deteriorating measurement accuracy.SOLUTION: The number of components and the required space of a spectral optical system can be reduced by using a rotation diffraction grating 110 to spectrally separating reflected light from a measurement object 10. An optical path for acquiring a measurement signal and an optical path for acquiring a reference signal can be shared, a required space can be reduced, and the accuracy of calibration can be improved by providing a reflection member 140 for reflecting light made incident from a measuring probe 106 and emitting the light to the measuring probe 106 in place of the measurement object 10. Consequently, the spectral optical system and an optical system for reference signal in particular can be minimized without deteriorating measurement accuracy. |
