<p>PROBLEM TO BE SOLVED: To smooth the surface even in a thin IC card by forming an antenna into a specific shape for preventing generation of unevenness resulting in uneven recording and for improving durability and to make the IC chip part position interminable by arranging an IC chip concealing layer for inhibiting illicit action and improving the durability. SOLUTION: In this IC card, a component including an antenna coil constructed of a winding coil and an IC module constructed of the IC chip is installed in a predetermined position between a first sheet member 1 and two supporting bodies facing a second sheet member 2, and the IC card is filled with an adhesive. The antenna coil and the shape of the antenna coil in the connection part between the antenna coil and the IC chip satisfy a particularly determined relationship. For covering the IC chip or a reinforcement board by at least 5% or more, the IC chip concealing layer is arranged, and the IC chip concealing layer is formed of either of the first sheet member and the second sheet member.</p> |
