ABSTRACT:
The present invention provides a resonance circuit tag that comprises an insulating substrate and a resonance circuit formed on the substrate. Additionally, the resonance circuit contains at least a capacitor and an inductor. Further, a dielectric of the capacitor satisfies at least either being foamable by heating or being capable of changing its thickness by not less than 10% by heating. The resonance circuit of the present invention also provides various advantages in that it can easily cease functioning, it does not inhibit labor-saving and speedy operation at the cash register, it facilitates large-scale production, and it eliminates degradation of the function of the article to which the tag has been attached.
