Disclosed are a wireless IC tag, reader/writer, and information processing system capable of improving energy transmission efficiency and increasing communication distance. The wireless IC tag is provided with a wireless IC chip (10) and two coil-shaped antennas (20A), (20B). One end of each of the coil-shaped antennas (20A), (20B) is electrically connected to the wireless IC chip (10), and the other ends are electrically connected to each other. In addition, the coil-shaped antennas (20A), (20B) are arranged at positions having different respective winding axes, and the winding directions are the same. Furthermore, the reader/writer (50) is provided with an antenna (52) connected to an information processing circuit (51), and this antenna (52) and the coil-shaped antennas (20A), (20B) electromagnetically couple and communicate. |
