Abstract: A wireless-IC-device main component is disposed on a surface opposite to a surface for receiving signals from a reader/writer. The wireless-IC-device main component includes an insulating substrate, which is provided with a loop electrode and an electromagnetically coupled module coupled to the loop electrode. A signal from the reader/writer causes an eddy current to flow across a conductor principal plane of a metal article. The eddy current causes a magnetic field to be generated in a direction perpendicular or substantially perpendicular to the conductor principal plane of the metal article. Then, the loop electrode is coupled to the magnetic field. Thus, the wireless-IC-device main component functions as an RFID tag even for signals from the principal plane opposite to the wireless-IC-device main component. Thus, it is possible to reduce the cost of manufacturing a metal article, and to provide a wireless IC device using the metal article as a radiator.
