Abstract: A distance measuring device provided with measuring means for acquiring a transmission timing at which a probe packet was transmitted to a probe target, and a reception timing at which a response packet to the probe packet was received from the probe target; response time calculating means for calculating a response time by using the transmission timing and the reception timing; medium storing means for storing a medium velocity, which is a signal transmission velocity in a transmission medium used for transmission between a distance measuring device and the probe target; and distance calculating means for calculating a distance to the probe target by using the response time and the medium velocity.
