<p><P>PROBLEM TO BE SOLVED: To provide a highly durable coin-shaped RFID tag in which the molded joint face of a disk-shaped edged resin case and a cover-shaped part are hardly peeled from each other even when an expansion/contraction stress is repeatedly applied due to a change in environment over time, especially a cyclic change in temperature. <P>SOLUTION: The coin-shaped RFID tag having almost uniform thickness is configured by molding a cover-shaped part 10 by applying injection molding to an intermediate product (figure 2) configured by continuously or intermittently forming at least one round rib 8 across the whole periphery of an edge part 4 of a disk-shaped edged resin case 2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
