<P>PROBLEM TO BE SOLVED: To obtain a compact and inexpensive wireless IC device capable of mounting a wireless IC chip easily, and to obtain electronic equipment mounting the wireless IC device. <P>SOLUTION: The wireless IC device has the wireless IC chip 5 processing transmission and reception signals, and a feeder circuit board 10 including a resonance circuit having an inductance element. On the surface of the feeder circuit board, there are external electrodes 19a, 19b coupled to the resonance circuit electromagnetically. The external electrodes 19a, 19b are connected to radiation plates 21a, 21b provided on a printed-wiring board 20 electrically in a continuity state. The wireless IC chip 5 is operated by a signal received by the radiation plates 21a, 21b, and a response signal from the wireless IC chip 5 is radiated outside from the radiation plates 21a, 21b. <P>COPYRIGHT: (C)2009,JPO&INPIT |
