Abstract

An IC card includes a terminal board at one end of and projecting from an obverse side of the circuit board, an IC module mounted on the reverse side, all embedded in a plastic body with an electrode terminal exposed through the body.

Claims

1. An IC card comprising:

a circuit board having two opposed ends, opposed obverse and reverse surfaces, and including interconnection circuitry disposed on the reverse surface;

a terminal board disposed at one end of the circuit board and projecting from the obverse surface of the circuit board, the terminal board having an obverse side spaced from the obverse surface of the circuit board;

at least one electrical terminal projecting from the obverse side of the terminal board and electrically connected to the interconnection circuitry;

an IC module mounted on the reverse side of the circuit board and electrically connected to the interconnection circuitry;

and

a card base body of synthetic resin having opposed obverse and reverse sides in which the circuit board, the IC module, and the terminal board are embedded with said electrical terminal exposed at the obverse side of the card base body.

2. An IC card according to claim 1 wherein said card base body has two opposed ends comprising a pair of guide grooves disposed in one of the ends of said card base body having a depth from the reverse side of said card base body to the reverse surface of said circuit board and extending in the direction in which said IC card is inserted into external equipment.

3. An IC card according to claim 2 including at least a pair of positioning recesses having a depth from the obverse side of said card base body to the obverse surface of said circuit board at the end of the circuit board adjacent said terminal board.
