A communication device location specifying system has a plurality of wireless communication devices, a location specifying device that specifies locations of the plurality of wireless communication devices, and a plurality of access points that are wirelessly connected to the plurality of wireless communication devices and relay the exchange of data between each wireless communication device and the location specifying device. Each of the wireless communication devices measures the intensity of an electric wave received from each of the access points, and transmits electric wave intensity measurement data indicating the measured intensity of the electric wave to the location specifying device via the access point, and the location specifying device calculates the locations of the plurality of wireless communication devices on the basis of the electric wave intensity measurement data.
