ABSTRACT:
A non-contact IC card has a high mechanical strength with respect to bending and twisting, although thin, yet allows the mounting area of a circuit board to be effectively used. A highly rigid, electrically-conducting reinforcing frame is disposed on the outer edge of a circuit board to increase the mechanical strength of the card with respect to bending and twisting. Further, the reinforcing frame is electrically connected to conductor patterns of a spiral coil on the circuit board having an inductance L in an antenna circuit.
