<P>PROBLEM TO BE SOLVED: To provide a card medium with built-in resonance tag which has excellent durability without being restricted in identifiable number and kind and can be manufactured by a simple and inexpensive method by integrally and simultaneously manufacturing a card main body with built-in resonance tag in a prescribed manufacturing process. <P>SOLUTION: This card medium is provided with: the resonance tags (e.g. 2a, 2b, and 2c) for oscillating an echo wave whose frequency is the same as that of an electromagnetic wave at the time of receiving the action of an electromagnetic wave with predetermined frequency; and the card main body 4 integrally and simultaneously manufactured with the resonance tags in a predetermined manufacturing process. In the manufacturing process, the resonance tags are printed in a status that the card main body is developed, and then the card main body in the developed status is overlapped, thereby manufacturing the card main body with built-in resonance tag. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
