Abstract
Abstract In an IC card in which an IC module constituted by a terminal plate 1 having a connection terminal pattern(3), arranged on a surface of an insulating substrate (2), for external power supply, signal connection, and grounding, an IC chip (4) mounted on the rear surface of the terminal plate 1 and electrically coupled to the connection terminal pattern (3), a sealing member (5) for the IC chip, and a reinforcing member (6) for reinforcing the sealing member (5) is mounted on a card base, the reinforcing member (6) consists of a conduction material, and integrally constituted by a ring portion (7) for covering the outer periphery of the sealing member (5) and a flange portion (8), having almost the same shape as that of the outer periphery of the terminal plate (1), for covering the rear surface of the insulating substrate (2). Therefore, an IC card which is strong to damage caused by disconnection of a bonding wire due to peeling between the insulating substrate and the sealing member caused by external force can be provided at low cost.
