Abstract
The reliability of a thin semiconductor card, such as an IC card, is enhanced by stress absorbing part such as deformable part for absorbing externally applied stress, thereby preventing the stress from damaging the card main body, the semiconductor module, or the semiconductor elements. Alternatively, protection is provided by a weaker section, located away from the semiconductor module, that breaks under external stress before the stress can destroy the semiconductor module.
