Ic card and method for producing the same |
摘要 |
Noises from an IC card generated during communications by the IC card are removed to exclude adverse effect on the operation of a peripheral apparatus. In an IC card (C 1 ) formed by sandwiching a circuit board ( 10 ) formed with an antenna pattern ( 1 A) and an IC chip ( 2 ) mounted on the circuit board with a plurality of card constituent sheets, ferrite beads ( 11 a, 11 b) for absorbing and removing noises (unnecessary radiation energy) inputting to and outputting from the IC chip ( 2 ) are mounted on wiring sections ( 12 a, 12 b) interconnecting the antenna pattern ( 1 A) and IC chip ( 2 ).
