れている。For example, a method of covering the periphery of the electrode part with a shielding electrode connected to ground is shown in Japanese Patent Application Laid-Open No. 57-188849 "Device for Protecting Electronic Circuits from Electrostatic Charge",
In addition, each electrode of the electrode section is formed on a semiconductive circuit board, a resistance element is connected between each of the electrodes, and a semiconductive adhesive material is attached across each of the electrodes. A method of providing a minute current path between each electrode of the electrode part and taking measures against static charge by adopting a structure in which this is done is described in Japanese Unexamined Patent Publication No. 59-22353, "IC Card"; Publication No. 59-22354 “IC card”

生じ、新たな問題が発生する。Problems to be Solved by the Invention As mentioned above, countermeasures against static charges in IC cards are an extremely important problem, and various countermeasures are being proposed. With the above method of using shielding electrodes, the probability that static charge is inadvertently applied to each electrode decreases, but it cannot be reduced to zero.Also, the method of providing a minute current path between each electrode reduces the If the impedance of the current path is large, the rise in potential due to static charge is large, so it is not a complete countermeasure against static charge.If the impedance of the current path is lowered, signal leakage will occur between each electrode, creating a new problem.
