Of an IC card, an IC is mounted on a surface of a circuit board (FPC) including a hard plate member that is attached on the other surface of the circuit board. Both surfaces of the circuit board having the IC and plate member are covered by a hard material member of electric insulating. Therefore, stress load applied to the IC can be restricted. Further, the circuit board along with the hard material member is divided into multiple portions that are connected using a flexible electric wiring. This can provide sufficient flexibility to the IC card, resulting in enhancement of a preventive effect in breakage or damage of the IC card.
