る必要がたかまつている。(Prior Art) The development of electronic engineering has been remarkable in recent years, and electronic devices are becoming extremely diverse. Many electronic devices now emit electromagnetic waves for their original purpose, such as communication, or as secondary noise from other devices. Such electromagnetic waves often interfere with the normal functioning of other electronic devices, and there is a growing need to block the harmful effects of electromagnetic waves.

い。 Many proposals regarding shielding of electromagnetic waves have been made and put into practical use. The simplest method is to construct the housing of the device from a material that absorbs or reflects electromagnetic waves, such as a metal material. However, this method of covering with a metal material has the disadvantage that it cannot be applied to cases where transparency is required, such as the front panel of a display device or the cover of a CRT. Also, methods of applying conductive paint and methods of zinc welding have been put into practical use, but these also impair transparency and do not solve the problem.

現状である。 For this reason, attempts have been made to form a conductive film on the surface of a transparent substrate, but this does not solve the fundamental problem as there are concerns that the conductive film may peel off, become contaminated, or deteriorate due to moisture or gas. The current situation is that this is not the case.
