Each semiconductor chip included in an information card according to this invention is enclosed in a metallic casing and roofed by a cover film. A conductor strip, extending from each of contacts of the semiconductor chip, is attached to the metallic casing through an insulative material. An electrically conductive elastic member having a magnet at its free end is provided in the metallic casing at a location corresponding to the conductor strip. When the conductor strip is not in contact with its corresponding signal input/output terminal, it is maintained in contact with the elastic member so as to electrically connect itself with the metallic casing through the elastic member, whereby connecting all conductor strips together and protecting the semiconductor chip from electrostatic breakdown.
