PROBLEM TO BE SOLVED: To allow simple and excellent blood sugar level measurement without requiring near-infrared spectrum measurement in a wide wavelength range.SOLUTION: In measurement of glucose concentration in a tissue of an organism with the use of a signal obtained by receiving light that has been diffused and reflected from or transmitted through the organism tissue after irradiation of near infrared light to the organism. The near-infrared light to be used includes near-infrared light of a first wavelength selected from a wavelength range of 1600±40 nm corresponding to an absorption peak wavelength of a glucose component and near-infrared light of a second wavelength selected from a wavelength range of 1400±20 nm for use in correction of a scattering coefficient variation in the organism tissue. |
