ABSTRACT:
An IC card comprising: an IC module including an IC-chip in which intrinsic information is stored at the stage of card manufacturing or card issuing and an antenna supported by an antenna supporting member; and two base plates between which the IC module incorporated with an adhesive layer; wherein hidden intrinsic information corresponding to the stored intrinsic information is recorded on a part of the antenna supporting member in such a way that the hidden intrinsic information is invisible by reflection light from the surface of the IC card and is read out from transmission light due to a transmission density difference between the recorded part of the hidden intrinsic information and a non-recorded part.
