WIRELESS IC DEVICE, CLIP-SHAPED RFID TAG, AND ARTICLE HAVING RFID TAG

摘要

In a wireless IC device, a columnar body includes a metal body with an insulating film. A loop-shaped antenna conductor is provided on an upper surface of the columnar body via an insulating pedestal. The loop surface of the antenna conductor is parallel or substantially parallel to the upper surface of the columnar body. On the lower surface of a RFIC element, two terminal electrodes are provided. The RFIC element is mounted on the antenna conductor such that the two terminal electrodes are connected to both ends of the antenna conductor, respectively. One end of the connecting conductor is connected to the vicinity of one end of the antenna conductor, and the other end of the connecting conductor is connected to the upper surface of the columnar body.
