Abstract
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.
