<p>PROBLEM TO BE SOLVED: To always secure the same capacity of a capacitor despite some mutual position shift caused between conductive tracks which are formed on both upper and rear sides of a substrate of a resonance label in its manufacturing process. SOLUTION: This resonance label consists of a substrate 1 of a plastic foil and plural conductive faces formed on both upper and rear sides of the substrate 1 together with some of conductive faces forming a capacitor in an area 5 where these conductive faces overlap each other. In such a constitution, an RFID label in particular consists of 1st and 2nd capacitor plates 3 and 4 formed on the upper and rear sides of the substrate 1 respectively and can be electrically detected. Both plates 3 and 4 have oblong shapes like belts having fixed width through their whole lengths and also partly overlapping each other. This area 5 is located with spaces secured to both ends of at least the plate 3 or 4.</p> |
