<P>PROBLEM TO BE SOLVED: To provide an object with RF function that communicates with a non-contact IC tag even when a lot of objects are stacked. <P>SOLUTION: An object 10 with RF function comprises: a plate 11 which is nearly circular in plan view; and an IC chip 12 and an antenna 13 mounted on the plate 11 and electrically connected with each other. On the inside of a bottom rim 17, the antenna 13 is arranged on the back surface 16b of the plate body 16 so that the center of gravity C<SB POS="POST">11</SB>of the plate 11 may not overlap the center of gravity C<SB POS="POST">12</SB>of the antenna 13. On the outer periphery of the plate 11, marks 14 and 15 for indicating the arrangement of the antenna 13 are formed at equal intervals around the center of the plate 1, while allowing the marks to be seen from the side at least when the plates 11 are stacked. <P>COPYRIGHT: (C)2012,JPO&INPIT |
