IC CARD, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To exclude an adverse effect in an operation relative to a peripheral apparatus by removing noise from an IC chip which is generated in the communication of the IC card.

SOLUTION: The IC card C1 is constituted such that a circuit board 10 with an antenna pattern 1A formed thereon and the IC chip 2 mounted on it are held between a plurality of card structure sheets. Ferrite beads 11a, 11b for absorbing and removing noise (unnecessary radiant energy) coming-in/going-out of the IC chip 2 are mounted on wiring parts 12a, 12b which connect the antenna pattern 1A to the IC chip 2.
