<p><P>PROBLEM TO BE SOLVED: To communicate with the same wireless communication apparatus in a normal manner, in a state where a wireless tag is attached to a metal object and in a state where the tag it is separated from the metal object. <P>SOLUTION: A tag body 30 comprising a tag antenna 31 and an IC chip 32, an elastic body 21, a resonance frequency adjusting means 40 including a coil 41 and an adjustment capacitor 42, and a protruding member 20 protruding from a mounting surface 10T are provided in the wireless tag 10. In a state where the wireless tag 10 is separated from the metal object 7, the resonance frequency adjusting means 40 is arranged, at a separate position R which does not magnetically influence the tag antenna 31, and where thee resonance frequencies of the tag body 30 and a reader/writer 5 match. By mounting the metal object 7 on the wireless tag 10, the protruding member 20 is housed in the wireless tag 10, the resonance frequency adjusting means 40 is displaced to an approaching position S which magnetically influences the tag antenna 31, and the resonance frequency of the wireless tag 10 which is affected by the metal object 7 is shifted to that of the reader/writer 5. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
