<P>PROBLEM TO BE SOLVED: To provide an RFID data carrier enabling miniaturization of a tag without reducing a communication distance to an input-output device. <P>SOLUTION: An IC chip 2 is supported to a support piece 4; a loop antenna 3 formed of a single antenna wire body 5 is disposed outside the support piece 4; and both ends of the wire body 5 are detachably connected to the support piece 4 in a form capable of securing electrical connection to the IC chip 2. Therefore, the size of the loop antenna 3 is prevented from being reduced even if the support piece 4 is miniaturized, so that the communication distance is prevented from being reduced. <P>COPYRIGHT: (C)2004,JPO |
