<p>An information leakage protective film, a portable small article storing case, a card case, and an information leakage protective plate. In the portable small article storage case (1), a side (C-C area) on the closed side is sewn, a base cloth (5) forming the front surface of the storage case is stacked on a base cloth (6) forming the rear surface thereof, the end parts of the stacked base clothes are sewn to each other with a yarn (7), the end parts are treated with another cloth, and its front and rear surfaces are inverted to form a bag shape. A laminated film (information leakage protective film) (10) is stacked on the base clothes (5) and (6), and the laminated film (10) is also sewn together with the base clothes (5) and (6) when the sewing above is performed. The laminated film (10) is formed by alternately laminating aluminum foil layers (12) and resin layers (13) on each other. Since the laminated film (10) formed of the aluminum foil layers (12) and the resin layers (13) is installed on the entire inner surface of the portable small article storing case (1), electromagnetic wave emitted from a card does not leak from the storing case to the outside and, therefore, the information in the card is not skimmed.</p> |
