PROBLEM TO BE SOLVED: To provide a round rod inspection device capable of easily detecting the flaw or the like of the outer peripheral surface of a round rod by a simple device only consisting of a light source and a light detection sensor, and to provide a round rod inspection method. SOLUTION: The round rod inspection device is equipped with the light source for irradiating the outer peripheral surface of the round rod with light almost vertically with respect to the axis of the round rod and the light detection sensor provided so that its angle formed with the incident direction of the light source in the axis of the round rod is above 90° to below 180°. The reflected light from the outer peripheral surface of the round rod of the light from the light source is detected by the light detection source and the outer peripheral surface of the round rod is inspected from the level of the detected light.
