Abstract: A component concentration measurement device includes a light application unit that applies pulsed beam light of a wavelength that is absorbed by a target substance for measurement to a site of measurement, and a detection unit that detects a photoacoustic signal generated in the site of measurement where the beam light emitted from the light application unit has been applied.
