WIRELESS IC DEVICE AND COMPONENT FOR A WIRELESS IC DEVICE

摘要

To provide a small and low-profile component of a wireless IC device and the wireless IC device while increasing the mechanical strength and the environment resistance performance of a wireless IC chip. A component (20A) of a wireless IC device including a wireless IC chip (5) and a feeding circuit substrate (10) on which resin layers are laminated. The wireless IC chip (5) is incorporated inside the feeding circuit substrate (10), and an annular electrode (25) is arranged inside the feeding circuit substrate (10). The component (20A) of a wireless IC device and the radiation plate constitute the wireless IC device.
