PROBLEM TO BE SOLVED: To provide a highly reliable composite IC card which is excellent in communication sensitivity.SOLUTION: A composite IC card comprises: a contact IC module 200 that communicates with an external reading/writing device by contacting a contact point of the external reading/writing device; and an antenna 250 that communicates with the external reading/writing device in a noncontact manner. In the composite IC card, the contact IC module 200 and the antenna 250 are magnetically coupled by an electromagnetic coupling coil 20 provided in the contact IC module 200 and an electromagnetic coupling coil 25 provided in the antenna 250. A high magnetic permeability member 207 reducing flux leakage is arranged between the electromagnetic coupling coil 20 and the electromagnetic coupling coil 25. |
