The present invention relates to a device for examining nerve function. In order to examine the function of a nerve of the human body, the device for examining nerve function of the present invention includes: at least one stimulator for stimulating the human body and a stimulator-fixing member having a form corresponding to the hands or feet of the human body, wherein the stimulator is located at one side of the simulator-fixing member so as to fix the stimulator to the hands or feet of the human body. The device for examining nerve function of the present invention further includes at least one blood-circulation detection sensor fixed at the stimulator-fixing member. According to the present invention, since the degree of hypoesthesia is examined through the stimulation of the stimulator, test accuracy and reliability may be greatly improved and it is possible to systematically and actively determine a diagnosis and course of treatment for a patient having diabetes or spinal nerve damage, e.g. hypoesthesia.
