ABSTRACT:
Composite sheet material, used for shielding magnetism and electromagnetic waves, principally made of an electrodeposited iron foil, as the core, with a thickness of at least 10 .mu.m which is applied on either side surface thereof a plating layer with a respectively predetermined metal, and of, a covering layer which is formed of a suitable sheet-like material and which is to be laminated on at least one of the two plating layers through the medium of an adhesive layer. A variety of products utilizing this composite sheet material as an essential elements thereof which stretches over a wide field wherein magnetic and electronic shield is required, for example: magnetic-card holders; magnetic-card protection cases or boxes; envelopes and containers for keeping and transporting magnetic recording media; wallpapers for various special rooms, etc.
