PROBLEM TO BE SOLVED: To propose a new concentration measurement device or the like capable of performing calibration and concentration measurements of a predetermined component even in a usage state where the concentration measurement device or the like is mounted on a predetermined portion of a living body.SOLUTION: Measurement light generated by a multiple wavelength light source 10 is caused to branch at a branch section 20, and first measurement light is irradiated to a living body by a first irradiation section 30A. An observed scattered light time-resolved waveform acquisition section 120 acquires an observed scattered light time-resolved waveform on the basis of light intensity of scattered light from a living body detected by a first light intensity detection section 70A. On the other hand, second measurement light caused to branch at the branch section 20 is irradiated to a reflection mirror 40. A device function time-resolved waveform acquisition section 130 acquires a device function time-resolved waveform on the basis of light intensity of reflection light detected by a second light intensity detection section 70B at the time of detection of the first light intensity detection section 70A. A scattered light time-resolved waveform correction section 140 performs deconvolution processing of the observed scattered light time-resolved waveform by the device function time-resolved waveform and calculates a scattered light time-resolved waveform. Further, a concentration calculation section 150 calculates the glucose concentration of the dermis layer of the skin by using the scattered light time-resolved waveform. |
