The invention discloses a noninvasive blood sugar detection device based on a raman scattering spectrum. The noninvasive blood sugar detection device based on a raman scattering spectrum comprises a semiconductor laser, an optical fiber beam splitter, an optical fiber probe, a light filter, a raman spectrometer, a first circuit switch, a second circuit switch, a phase locking amplifier, a heart rate measuring apparatus and a computer. According to the noninvasive blood sugar detection device based on a raman scattering spectrum disclosed by the invention, raman scattering light contains rich molecular vibration information, the characteristics that the raman scattering spectrum having different molecules has different features are utilized, the raman scattering spectrum is used for recognizing molecules; and through the relative value of a glucose characteristic peak at the position of 1125cm-1 in the raman scattering spectrum in pure blood to the hemoglobin characteristic peak value at the position of 1549cm
