    Abstract: In a plastic card (10) for an embossing finish comprising a core material (12) and a sheath material (13), a breaking elongation of the core material (12) is 25 % or less and a breaking elongation of the sheath material (13) is 130 % or more. The ratio of the thickness of the core material to the thickness of the sheath material (13) occupied in the entire part of the plastic card is set to 20 to 53 : 10. Otherwise, a breaking elongation of the core material (12) is 50 % or less and the tensile strength of the sheath material (13) is 100 MPa or more. The ratio of the thickness of the sheath material (13) to the thickness of the core material (12) occupied in the entire part of the card is set to 41 to 90 : 10. The breaking elongation of the core material (12) and the sheath material (13) or the tensile strength of the sheath material (13), and the ratio of thickness of the core material (12) to the sheath material (13) are adjusted so that the plastic card excellent in embossing characteristics and hardly generating cracks due to a repetitive bending fatigue is provided.

    Abstract: To provide an IC card, which secures satisfied flatness of the card surface to achieve good printing properties on the card surface. An IC card has a core layer which includes a plurality of sheet materials wherein inner core sheets adjacent to an IC module have through holes formed in a region corresponding to the IC mounted portion, wherein a relationship A=(B 1 +C 1 )±30 mum is satisfied, where A (mum) represents the sum of heights of the through holes, B 1 represents a projection height on an IC mounted surface of the IC module, and C 1 represents a projection height on an IC non-mounted surface. By virtue of having this structure, the IC card can secure card flatness sufficient to obtain satisfied printing properties with respect to the rewrite sheet.
