8、e self-monitoring of blood glucose (SMBG) is necessary and indispensable to treat the diabetic. However, present SMBG has been limited to the measurement that needs collecting blood. The patient has loads of pain, stress

9、, and costs, etc. Therefore, the non-invasive blood glucose meter to be able to measure the blood glucose level is strongly expected [3-5]. In the present study, the confocal optical system has been constructed by using

10、the near-infrared laser, and the reflection photodetection system of the living body has been developed. And the initial experiment for the development of the non-invasive blood glucose meter that presumed the blood gluc
