RESONANCE CIRCUIT TAG AND ITS MANUFACTURE, AND METHOD FOR VARYING ITS RESONANCE CHARACTERISTIC

摘要

PURPOSE: To provide a resonance circuit tag which is easily manufactured and has a superior self-breaking function and exerts a little adverse influence on an article, and a method for manufacturing the tag advantageously, and also a method for easily and surely varying resonance characteristics of the new resonance circuit tag obtained by the manufacturing method. CONSTITUTION: The function of the resonance circuit tag T is stopped by varying the thickness by heating the dielectric of the capacitor 2 of the resonance circuit tag formed by providing an insulating base material 4 which a resonance circuit having a capacitor 2 and a coil 1. One of a primary and a secondary circuit is laminated on a base and the other circuit is laminated on the laminated body through an adhesive layer to manufacture the resonance circuit tag T.
