Component Concentration Measurement Device

A component concentration measurement device comprising:

• a light that applies beam light to a site of measurement, the beam light having a wavelength that is absorbed by glucose;
• a detector that detects a photoacoustic signal which is generated at the site of measurement where the beam light has been applied;
• a moisture measurer that measures an amount of moisture in skin at the site of measurement;
• and
• a corrector that corrects an acoustic signal detected by the detector in accordance with the amount of moisture measured by the moisture measurer.

A method comprising:

• applying, by a light, beam light to a site of measurement, the beam light having a wavelength that is absorbed by glucose;
• detecting, by a detector, a photoacoustic signal which is generated at the site of measurement where the beam light has been applied;
• taking a moisture amount measurement of skin at the site of measurement;
• and
• correcting an acoustic signal detected by the detector in accordance with the moisture amount measurement.
