Abstract:
1. An IC card comprising: an IC module which comprises an IC chip mounted on an insulating substrate, a sealing resin encapsulating said IC chip on said insulating substrate such that said sealing resin provides a protective encapsulation about said IC chip, and a reinforcing sheet provided over said IC chip with said sealing resin therebetween; a card substrate comprised of a resin within which said IC module is sealed; and a reversible display layer provided on at least one surface of said card substrate, wherein, said card substrate has a surface flatness suitable for printing with respect to said reversible display layer, said IC chip module includes a reinforcing film pattern between said IC chip and said insulating substrate having an opening which exposes at least a portion of said IC chip facing said insulating substrate, an outer periphery of the reinforcing film pattern on the IC chip side of the insulating substrate is larger than an outer periphery of the reinforcing sheet, and the opening of the reinforcing film pattern is smaller than the outer periphery of the reinforcing sheet.
