ABSTRACT:
The invention provides an IC card in which it is difficult to separate IC chips from the IC card. In accordance with the invention, an IC card formed by laminating a plurality of substrates can include a sensor for identifying an authorized person, a signal processing circuit for processing the identification based on an output from the sensor and a card-shaped card medium containing the sensor and the signal processing circuit. At least the signal processing circuit can include a thin film circuit which is sufficiently thinner than the card medium and contains a material which is dissolvable equally to or more than the card medium.
