<p>Provided is a wireless IC device including a wireless IC chip on which shock or the like does not directly act from the outside. A wireless IC device 10 includes (a) a radiating plate 11, (b) a wireless IC chip 24, and (c) a feeder circuit board 22, 22a on which the wireless IC chip 24 is mounted. The feeder circuit board includes a resonant circuit with an inductance element, and the resonant circuit is electromagnetically coupled with the radiating plate 11. The wireless IC chip 24 is interposed between the radiating plate 11 and the feeder circuit board 22, 22a.</p> |
