〈産業上の利用分野〉
本発明はＩＣカードに係わり、特に、半導体集積回路を
内蔵し、人に携帯されるＩＣカードに関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an IC card, and more particularly to an IC card that includes a built-in semiconductor integrated circuit and is carried by a person.

点があった。<Problems to be Solved by the Invention> In the IC card having the above structure, the surface of the electrode protrudes from the insulating card surface, and since the IC card is carried by a person, it is difficult to When an electrode touches a human body, the static electricity charged on the person is applied from the electrode to the semiconductor integrated circuit through the conductor thin film, making it necessary to increase the voltage resistance of the semiconductor integrated circuit, and expensive high voltage integrated circuits are required. There is a problem in that the use of circuits increases the price of the IC card.

うにしたことを要旨とする。Means for Solving the Problems> In view of the use of expensive, high-voltage semiconductor integrated circuits in the conventional IC cards, the present invention is aimed at preventing the human body from directly touching the electrodes even if a charged human body touches the IC card. The main feature is that the surface of the electrode is disposed inward from the surface of the IC card, and a conductor is provided near the electrode so that static electricity is discharged from the conductor.

A conductive thin film connects the semiconductor integrated circuit and the electrodes 2-6. A comb-shaped conductor 7 is adhered to the surface of the card 1, and this 7 and the electrodes 2 to 6 are arranged so that the surfaces of the electrodes 2 to 6 are conductive, as shown in detail in FIG. It is located inside the surface. This conductor is connected to the ground terminal of the semiconductor integrated circuit through one path of the conductor thin film.

It is never applied to the circuit.

As a result, the semiconductor integrated circuit can be made into an inexpensive general-purpose product, and the price of the IC card can be reduced.
