1. An electronic device comprising:
a sensor configured to acquire a subject's pulse wave in a non-invasive manner;
a blood pressure measurement portion, including the sensor or a second sensor, configured to measure the subject's blood pressure level in a non-invasive manner;
a controller configured to automatically determine a rising index based on the subject's pulse wave acquired by the sensor, automatically estimate a blood glucose level of the subject on the basis of the determined rising index and the subject's blood pressure level measured by the blood pressure measurement portion; and
a communication interface configured to transmit to an external apparatus the blood glucose level of the subject estimated by the controller in real time, or a notification interface configured to notify the subject of the blood glucose level of the subject estimated by the controller in real time,
wherein the rising index is a ratio of a first local minimum to a first local maximum in an acceleration pulse wave yielded by a second derivative of the subject's pulse wave.
