Wireless IC device and method for manufacturing same
A wireless IC device which functions as a non-contact RFID system even when the wireless IC device is attached to an article containing metal, water, salt or the like, without hindering reduction in size and thickness, and a method for manufacturing the same are obtained. The wireless IC device includes a wireless IC chip arranged to process a predetermined wireless signal, a feed circuit board on which the wireless IC chip is mounted, a loop-shaped electrode that is coupled to the wireless IC chip via the feed circuit board, and a first electrode plate and a second electrode plate that are coupled to the loop-shaped electrode. The loop-shaped electrode is sandwiched between the first electrode plate and the second electrode plate and is arranged such that the loop surface thereof is perpendicular to or tilted with respect to the first and the second electrode plates. At least the first electrode plate out of the first electrode plate and the second electrode plate is used for transmission and reception of the wireless signal.
