<P>PROBLEM TO BE SOLVED: To provide a radio tag capable of reading and writing information more easily by short distance communication of an electrostatic coupling system, an electromagnetic induction system, or the like. <P>SOLUTION: An antenna part 64 is composed of at least two linear elements connected to an IC circuit part 80 and an induction pattern part 150 is constituted on the side which is not connected to the IC circuit part 80 in the respective linear elements. Thus, by performing electrostatic coupling between the induction pattern part 150 and an electrode 54 provided on a radio tag generation device 12 and performing electromagnetic induction between the induction pattern part 150 as a secondary coil and a primary coil 148 equpped with the raio tag generation device 12, information can easily be read and written with a relative distance kept between the antenna part 64 and the electrode 54 or between the antenna part 64 and the primary coil 148. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
