IC CARD AND PRODUCING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To enable a stable conduction/connection between an IC module substrate and an antenna coil in an IC card. SOLUTION: An antenna coil 13 connecting a coil terminal 17 to the terminal part is embedded in an IC card substrate 10. On the other hand, an IC module 20 has a lead terminal 22 connected to an IC module substrate 21, a connecting member 30a and a holding frame 23 and mounted on the IC card substrate 10. The connecting member 30a is formed into W-shaped waveform with a cross section having a curved part 31. Therefore, when mounting the IC module 20, the connecting member 30a contacts and connects these lead terminal 22 and coil terminal 17 respectively at plural spots. Thus, since a contact area is widened and contact resistance is reduced, stable conductivity is secured and a contact defect can be eliminated.
