A storage container for a floppy disk, which comprises an electroplating layer 4 of an iron-nickel alloy on the plating layer or via another plating layer 3, wherein the chemical plating layer has a thickness of The thickness of the electroplated layer of the iron-nickel alloy is about 1.0 to 5.0 μm. Then, these plated layers are formed by a conventional method. The iron-nickel alloy used in the present invention may be any iron-nickel alloy having a magnetic shielding property, and is usually an alloy containing 10 to 50% of iron component. Therefore, in the present invention, a synthetic resin container is preformed with a chemical plating layer of nickel or copper having a shielding effect against pulsed electromagnetic waves on the entire surface or one of the outer surface and the inner surface of the synthetic resin container. The alloy layer can be formed as an electroplating layer of an iron-nickel alloy having a good electromagnetic wave shielding property that cannot be directly subjected to chemical plating on the resin plate. -It has a complementary effect with the magnetic shielding effect of the nickel-based alloy layer. Further, in the case where a plating layer made of an iron-nickel alloy is formed on a chemical plating layer via a copper electroplating layer, an extremely large electromagnetic wave shielding effect can be obtained even if the chemical plating layer is thin.

Can be formed by electroplating, and since the nickel or copper metal layer itself also has a shielding effect against pulsed electromagnetic waves, these two layers can protect the floppy disk from various electromagnetic waves from the outside. Moreover, since it is lighter than the conventional product, it is effective as a storage box that is convenient to carry.
