Abstract
Provided is a composite IC card including: a card base having a recess; an antenna sheet arranged inside the card base; an IC module arranged in the recess of the card base. The IC module includes an IC chip having a module substrate provided with an external terminal, and a first coupling coil. The antenna sheet includes an antenna coil configured to perform reception of electric power and transmission and reception of signals with an external reader, and a second coupling coil connected to the antenna coil. The first coupling coil and the second coupling coil are arranged so as to be capable of achieving close coupling therebetween and configured to couple the IC module with the antenna sheet in a non-contact manner by trans coupling. The second coupling coil of the antenna sheet is arranged outside a region in which the recess of the card base is formed.
