Abstract
An IC card (1) has a base card (2), and an IC module (10) placed in a cavity (3) formed in one surface of the base card (2). The IC module (10) comprises a substrate (11), a contact layer (15) formed on one surface of the substrate (11), an IC chip (12) attached to the other surface of the substrate (11), and a frame (14) attached to the other surface of the substrate (11). A space defined by the frame (14) is filled up with an encapsulating resin (13) so as to encapsulate the IC chip (12). A deflection per unit length of the substrate (11) under a predetermined load is greater than that of the base card (2) under the same load. When a bending force is applied to the IC card (1), a portion around the IC chip (12) is protected by the encapsulating resin (13) and the frame (14), and portion of the substrate (11) other than the portion around the IC chip (12) is distorted greatly to absorb the bending force.
