PROBLEM TO BE SOLVED: To obtain an IC that is small in the decrease of sensitivity is small and can also add a card function. SOLUTION: This IC card comprises a card base 2 on which circuits including an antenna circuit 1 are formed, electronic parts such as an IC chip 3 connected to the base 2, surface layers 4 and magnetic stripes provided on the layers 4, and the circuit 1 crosses orthogonally the magnetic stripes. If a conductor is formed on the rear face of the magnetic stripes and used as a jumper connecting the circuit 1 and the electronic part such as the chip 3, it is desirable because an IC card can be manufactured, for instance, without forcedly housing the circuit 1 under an electronic part to be connected, reducing the interval of antenna coil lines and line widths nor lowering productivity. |
