The present invention is a non-invasive blood sugar detection device. Firstly, it will be explained that the present invention achieves a non-invasive testing technique. In normal life, people sweat more or less from their skin, and the sweat contains glucose. This element, and after glucose is decomposed, it will generate electron flow and cause voltage. When the blood sugar level in the human body is higher, the amount of glucose is more, and the sensor 2 of the present invention absorbs the electrons of glucose in sweat through the reaction liquid layer 23.
