Abstract
An electronic card includes a card terminal which is exposed on a surface of a card, a semiconductor integrated circuit chip including an insulated-gate field effect transistor, and a protection circuit which is provided between the card terminal and the insulated-gate field effect transistor. The protection circuit is configured to protect the insulated-gate field effect transistor from destruction against a pulse having a pulse width of 1 ns or less applied to the card terminal.
