    • An IC card having high reliability, which is not only in that printing can be surely conducted with respect to the reversible display layer provided on the surface of the card substrate, but also in that the IC chip is surely protected by the reinforcing sheet. An IC card which has: an IC module (1) including an IC chip (14) mounted on an insulating substrate (11), and a reinforcing sheet (16) provided over the IC chip (14) through a sealing resin (15) for sealing the IC chip (14); a card substrate (2) comprised of a resin for sealing the IC module (1); and a reversible recording layer (3) provided on at least one surface of the card substrate (2), wherein reinforcing film patterns (13), (13null) having openings (13a), (13anull) which expose the IC chip (14) mounted portion are provided on at least one of the IC chip (14) mounted surface and the non-mounted surface of the insulating substrate (11).
    • 相对于设置在卡片基板的表面上的可逆显示层,可以确实地实现了具有高可靠性的IC卡,不仅可以进行印刷,还可以确保IC芯片被加强片保护。 一种IC卡,其具有:IC模块(1),其包括安装在绝缘基板(11)上的IC芯片(14),以及通过密封树脂(15)设置在IC芯片(14)上的加强板(16) 用于密封IC芯片(14); 由用于密封IC模块(1)的树脂构成的卡片基板(2); 以及设置在所述卡片基板(2)的至少一个表面上的可逆记录层(3),其中,具有使所述IC芯片露出的开口(13a),(13a')的加强膜图案(13),(13' 14)安装部分设置在IC芯片(14)安装表面和绝缘基板(11)的非安装表面中的至少一个上。
