Zusammenfassung:	PROBLEM TO BE SOLVED: To solve a problem of a conventional optical measuring method for measuring the blood sugar level (glucose concentration), wherein the improvement of the accuracy in the measurement and the miniaturization of a device are not advanced. SOLUTION: Three kinds of single-wavelength laser beams (laser beams of three different wavelengths) are applied to a region to be measured, and the absorptance for each wavelength is measured. Then, a secondary differential value is computed from the three dispersive absorptances, and the blood sugar level is computed based on the conversion function between the secondary differential value and the blood sugar level. In this way, the accurate, miniaturized and non-invasive blood sugar level measuring device and blood sugar level measuring method can be provided. COPYRIGHT: (C)2008,JPO&INPIT
