Non-invasive blood glucose level measurement device (1) is provided with an impulse waveform measurement unit (2), has the FBG sensors (4) of an acceleration pulse wave for measuring a test subject The unit (3) of one data processing, is used for the time point in the measurement of acceleration pulse wave, and from the waveform information of measurement acceleration pulse wave, the blood glucose level of test subject is calculated based on a scheduled correlation. Association is the calibration curve by implementing PLS regression analyses construction, uses the acceleration pulse wave measured simultaneously as objective variable blood glucose level, as explanatory variable measured by a kind of non-invasive blood glucose method. When therefore an invasive blood glucose measurement device can obtain when can about the same measurement accuracy measurement blood glucose levels non-invasive blood glucose level measurement device.
