Description of the Related Art Conventionally, many electronic devices generate electromagnetic waves for their original purpose or as a by-product, and other electronic devices often receive the electromagnetic waves as noise and interfere with normal functions. Therefore, there is an increasing need to block the adverse effects of this electromagnetic wave. The electromagnetic wave shield of electronic equipment is an electromagnetic wave shield material (eg, metal material, conductive paint, electroless metal plating, etc.) that surrounds the part that generates electromagnetic waves.
It is possible to achieve this by covering it continuously, but in a computer terminal display device, a plasma display, and other display devices, the display part cannot be covered with a shield substance, so it is a cheap and easy-to-install transparent and electromagnetic shielding effective composite. Development of resin plate is required.

It is obtained by laminating a wire mesh or a mesh sheet 3 having an electromagnetic wave shielding effect between a pair of transparent synthetic resin plates 2. FIG. 5 is a typical example of this, in which transparent synthetic resin plates 2 and 2 are adhered together with an adhesive 42, and a mesh-like sheet 3 having an electromagnetic wave shielding effect is embedded in the adhesive 42 (actual exploitation 50). 36873). This transparent electromagnetic wave shield plate is a material that absorbs or reflects electromagnetic waves,

業者の疲労を増大させるなどの問題を有する。When a solution adhesive is used to bond the mesh sheet 3 and the synthetic resin plate 2 instead of using the adhesive film 41, the lower the viscosity of the adhesive is, or the surface of the filamentous material 31. The higher the affinity with, the more the liquid surface of the solution adhesive rises around the filament 31 due to the surface tension.
Moreover, since the surface of the adhesive does not become horizontal due to shrinkage during coagulation, there are problems that scattered light rays are scattered and an image is disturbed, and fatigue of an operator is increased.

＜ニ＞メッシュ状シートの一部が接着フィルムから露出

きる。
＜ホ＞メッシュ状シート単独で形成されたＶＤＴフィル
ターに較べ、メッシュ状シートに付着した埃の除去等、
メンテナンス性に優れたものが得られる。According to the present invention, the following effects can be obtained. <A> Since the conductive portion of the mesh sheet is exposed on the entire surface, it can be easily attached to an electronic device. <B> Since the conductive part of the mesh-like sheet is exposed on the entire surface, it is electrically continuous (sealed) by being crimped to the electromagnetic wave shielding housing even if it is cut into any size.
It is possible to enhance the electromagnetic wave shielding effect. <C> By using the adhesive film, the problems caused by the solution adhesive can be solved. That is, when a solution adhesive is used, the liquid surface rises around the filament due to surface tension,
Further, since the surface of the adhesive does not become horizontal due to shrinkage at the time of solidification, there are problems that scattered light rays are scattered and an image is disturbed, and fatigue of the operator (techno stress) is increased. <D> Since a part of the mesh-like sheet is exposed from the adhesive film, the reflection image is not reflected on the surface of the filter, images and characters do not flicker, and the antiglare property can be enhanced. <E> Compared to a VDT filter formed by a mesh sheet alone, removal of dust adhering to the mesh sheet, etc.
A product with excellent maintainability can be obtained.
