It is composed of an insulating layer 3 formed on both sides of a base fabric 1 coated with a base fabric 1. The metal layer 2 may have a single layer structure, but
It is more preferable to have a laminated structure in which the electric field shielding metal layer 4 and the magnetic field shielding metal layer 5 are overlapped and coated as in this embodiment. When the metal layer 2 has a single layer structure, the sheet-like base fabric I The front and back sides of the sheet may be coated with the same electromagnetic shielding metal, or the front and back sides of the sheet base may be coated with different electromagnetic shielding metals (for example, one side is covered with an electric field shielding metal,
Other surfaces may be separately coated with a magnetic field shielding metal.

ールド性金属を被覆してもよい。The base fabric 1 is suitably constructed in the form of a woven fabric, knitted fabric, or nonwoven fabric using synthetic fibers, natural fibers, inorganic fibers, artificial fibers, or the like. Synthetic fibers are suitable as the fiber material for the base fabric 1. Specifically, synthetic fibers such as nylon, polyester, vinylon, acrylic, and polyurethane can be used. Among them, polyester has good strength, heat resistance,
In the present invention, the base fabric 1 has an aperture ratio of 5 to 5, which is most preferable because it has excellent durability, can create a good etched surface, and can improve the adhesion with the metal coated on it.
If a value of about 60% is adopted, there is an advantage that transparency can be ensured even in combination with a transparent insulating layer. The above-mentioned open area ratio refers to the proportion of the planar area of the spaces (voids) formed between each fiber yarn or converged fiber yarns constituting the base fabric l to the total planar area of the base fabric. Since the base fabric 1 can ensure transparency, it is possible to configure the sheet so that the total light transmittance of the entire sheet (according to JIS K 6745) is 10 to 50%. Examples of metals include aluminum, copper, gold, silver, nickel, and iron. Among these metals, copper, aluminum, gold, silver, etc. can be classified as electric field shielding metals because they have a rich electric field shielding effect, and nickel and iron have a rich magnetic field shielding effect, so they can be classified as electric field shielding metals. Can be classified as metal and used. As the metal for forming the metal layer 2, the above-mentioned metals may be used alone or in an appropriate combination. In the present invention, the above-mentioned electric field shielding metals and Magnetic field shielding metals are individually laminated and coated. In this case, normally, as in this embodiment (after coating with the electric field shielding metal layer 4,
The magnetic field shielding metal layer 5 is laminated thereon, but the magnetic field shielding metal layer 5 may be coated first with the electric field shielding metal depending on the purpose.

い点から繊維糸６に予め被覆形成することが好ましい。When coating the base fabric 1 with the above-mentioned metal, the fiber threads 6 constituting the base fabric 1 are usually coated as shown in FIGS. 2(a) and 2(b).
Preliminary coating is applied. In addition, coating may be formed on the base fabric 1 in the form of woven fabric, knitted fabric, or non-woven fabric, but especially when the base fabric is woven fabric or knitted fabric, it is possible to form a coating on the base fabric 1 in the form of a woven fabric, knitted fabric, or non-woven fabric. It is preferable to form a coating on the fiber thread 6 in advance in order to prevent spread such as separation from the fiber due to deformation.
