PROBLEM TO BE SOLVED: To read information under non-contact state remotely by providing an RF tag with the desired resonance frequency corresponding to a radio wave while printing an element on a substrate with a printing method. SOLUTION: This radio wave response sheet 29 is provided with an RF tag 30 and a substrate 31, and that RF tag 30 forms an almost helical coil 32 equipped with the desired resonance frequency corresponding to the radio wave while being printed on the substrate 31 as a tag formation with the printing method and an almost rectangular capacitor 33 formed integrally with the helical center part of this coil 32. Such a capacitor 33 is composed of 33a and 33b laminated at the helical center part of the coil. 32. This, the purpose of disposable use can be surely dealt with and the information can be read with no contact for the long distance. |
