Abstract:

An IC card having a card substrate and an IC module which is mounted on the card substrate. The IC module comprises a terminal board (1) including an insulating board (2) and a connection terminal pattern (3) for power supply, signal connection, and grounding formed on the insulating board (2), an IC chip (4) which is mounted on the back of the terminal board (1) and electrically connected to the terminal pattern (3), an encapsulating member (5) for encapsulating the chip (4), and a reinforcing member (6) for reinforcing the member (5). The reinforcing member (6) is made of a conductive material and comprises a ring section (7) which covers the periphery of the encapsulating member (5) and a flange section (8) which has nearly the same shape as that of the periphery of the terminal board (1) covering the back of the insulating board (2) both formed in one body. Therefore, an IC card such that breakage caused by disconnection of bonding wires resulting from the separation of the insulating substrate (2) from the encapsulating member (5) by an external force is produced at low cost.
