<p>A printed wiring board (10) for IC cards that can be built in or mounted on a contact-type IC card, i.e., on an IC card having external contact terminals. Bumpers (20) are formed on portions of conductor circuits (13) of the printed wiring board (10) for IC cards to make the bumpers (20) serve as external contact terminals. Thus, only the contact surfaces of the external contact terminals are exposed on the surface of the IC card (30) with the contact surfaces being flush with the surface of an over sheet (14). Therefore, there is provided a printed wiring board (10) for IC cards which completely prevents the IC module (12) from jumping out when the IC card (30) is bent, and in which the external contact terminals exhibit excellent electric contact reliability.</p> |
