Zusammenfassung:An IC card includes a main substrate and a plurality of sub-substrates. Each sub-substrate has two surfaces on which electronic components are installed. The sub-substrates are mounted on both surfaces of the main substrate within the IC card. Openings in the main substrate receive electronic components installed on the sub-substrates. Such an arrangement makes it possible to provide four layers of electronic components within an IC card.
