However, problems such as the occurrence of a failure due to electromagnetic waves from outside the facility or the leakage of communication contents due to the radiation of these radio waves to the outside of the facility are becoming problems.

This is one in which a patterned metal foil layer is arranged on a substrate such as a transparent resin film having electrical insulation. Such a patterned thin layer is mainly formed by etching a thin metal layer. is there.

In general, the basis weight of the fiber is too high, resulting in over-spec and high cost. Furthermore, in the case of woven fabrics, continuous processing is difficult and preformed woven fabrics are later processed with resin, so the number of steps increases, which is also a cause of high cost. In addition, unevenness and "openings" occur, and the aesthetic appearance required for use as, for example, an electromagnetic wave shielding material for a glass surface cannot be obtained. Similarly, even when cut fibers or chopped fibers are used, unevenness tends to occur, and a fiber having a sufficient appearance cannot be obtained.
