Abstract: The non-contact data carrier has a resin substrate, a metallic antenna coil on the resin substrate, and an IC chip connected to the antenna coil via a plurality of bumps. Each bump of the IC chip has a base on the side of the IC chip body of the data carrier and a projection held by the base via a shoulder. Each bump is connected to the antenna coil by piercing the projection into the antenna coil.

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.

Abstract: The IC card of the present invention comprises an IC card comprising an IC module embedded in a card substrate, said IC card having a reinforcing sheet layer laid in the planar direction of the card so as to cover at least the peripheral portion of the boundary between the card substrate and the IC module, and/or has a reinforcing member comprising at least a part of the side portion of said IC module extended in the outer circumferential direction, and it is excellent in mechanical strength and flexibility against bending of card.
