A non-invasive blood glucose level measurement device (1) is provided with a pulse waveform measurement unit (2) having FBG sensors (4) for measuring an acceleration pulse wave of a test subject； and a data-processing unit (3) for calculating the blood glucose level of the test subject at the point in time of measurement of the acceleration pulse wave, from waveform information of the measured acceleration pulse wave, on the basis of a predetermined correlation. The correlation is a calibration curve constructed by carrying out a PLS regression analysis, using the blood glucose level measured by a non-invasive blood glucose method as the objective variable, and a simultaneously-measured acceleration pulse wave as the explanatory variable. A non-invasive blood glucose level measurement device capable of measuring a blood glucose level at about the same measurement accuracy as an invasive blood glucose measurement device can be achieved thereby.
