In general, regardless of using an optical method or an electrical AC resistance impedance method, non-invasive blood glucose measurement has a problem in that variations in the level of glucose contained in blood are too small to be measured as a signal, and thus measurement results are inaccurate due to noises generated during measurement and errors caused by the difficulty in consistent measurement. To solve this problem, the present invention provides a non-invasive blood glucose sensor includes: a measurement-unit body; an impedance electrode sensor provided on an inner bottom surface of the measurement-unit body; a signal-generation and measurement unit configured to measure impedance while scanning frequency by supplying multiple frequencies to the impedance electrode sensor; a blood sensor configured to measure the amount of blood flowing through a body part brought into contact with the impedance electrode sensor; and a status display LED configured to display different colors according to the amount of blood measured using the blood sensor. Owing to this configuration, the present invention has an effect of measuring an accurate blood glucose level in a non-invasive manner.
