<P>PROBLEM TO BE SOLVED: To prevent the forgery of a sealing seal and to prevent a leak of the information of a document and the falsification of an object by securely detecting unsealing of a mouth of an object sealing the document or the object. <P>SOLUTION: The electronic sealing seal 1 comprises forming coils 3 on the rear face of a film-like or sheet-like insulative base material 2, oppositely forming capacitor patterns 4 and 7 on both front and rear faces of the insulative base material 2, thereby constituting a capacitor 11 via the insulative base material 2, and providing a resonance circuit 12 by the coils 3 and the capacitor 11. Wiring patterns 5 connecting one side electrode patterns of the capacitor 11 formed on the same side as the coil patterns or on the opposite side and the coils 3 to each other have intricately curved shapes and a tacky adhesives 13 or adhesives 6 are applied to the wiring pattern 5 side such that, when the sealing seal 1 is peeled from the sealed object after the seal sticker 1 is stuck on the sealed object, the wiring pattern 5 parts are peeled from the insulative base material 2, adhere to the object and the resonance circuit is destructed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
