Patent ID: 7531757

Claim:
An IC card, comprising: a semiconductor integrated circuit device package having one surface and another surface opposite to the one surface, which includes a wiring board, a semiconductor integrated circuit chip on the wiring board, and an insulating resin coated over the semiconductor integrated circuit chip to form the other surface of the integrated circuit device package; card terminals on the one surface of the semiconductor integrated circuit device package, the card terminals being electrically connected to the semiconductor integrated circuit chip, the card terminals being rectangular and extending in parallel to each other, an outermost of the card terminals being wider than the other terminals; and a base card, including a concave portion, attached to the other surface of the semiconductor integrated circuit device package, the base card including a card terminal surface and an opposite surface, wherein side walls of the semiconductor integrated circuit device package are spaced apart from the base card, and the card terminal surface of the base card includes a rib projecting from the card terminal surface on an end of the card terminal surface opposite to the apparatus insertion surface.
