Abstract
An IC card includes: a circuit board on which functional components are mounted; and a frame covered with a thin plate, the circuit board being disposed in the frame, the inside of the frame being filled with a foamed resin. As a result of the above arrangement, an IC card having a strong resistance to various external forces is produced. Furthermore, because it is possible to incorporate a surface material with a design in an integrally molded device, thus it is also possible to produce an IC card device having an excellent appearance.
