ARTICLE WITH WIRELESS IC TAG

The present invention relates to a variety of articles in which a wireless IC tag (20) mounted on a low magnetic permeability material is mounted on a holding part which has first and second surfaces and is made of a high magnetic permeability material. The holding part has a penetrating part which penetrates the first and second surfaces, and a notch which penetrates a part of the continuous first and second surfaces in a periphery of the penetrating part and makes the penetrating part communicate with outside. A discontinuous region (R) is formed on the holding part in the periphery of the penetrating part due to the notch, and at least on the penetrating part, the wireless IC tag (20) is tightly held together with the low magnetic permeability material. As a result, by providing the penetrating part and the notch, an axis of reverse direction magnetic flux generated by an eddy current that flows in the periphery of the penetrating part and the notch is shifted from an axis of the magnetic flux produced by electromagnetic waves directed toward the wireless IC tag (20) on the first and second surfaces, the effects of the magnetic flux due to the eddy current (I) are weakened, and communication with a reader/writer can be performed without troubles.
