それとともにクロ・ンク周波数の高周波数化が進められ
ている。[Prior Art] In recent years, various devices using electronic components such as microcomputers, such as office machines such as electronic typewriters and printers, household electrical appliances such as washing machines and vacuum cleaners, and fuel injection, have been electronically controlled. Automobiles, etc. that operate are rapidly becoming popular. The number of microcomputers used also increased,
At the same time, the clock frequency is being increased to a higher frequency.
ところが、この高周波数化のために、電子部品等の発生

外部磁界によって記録情報の消失といった悪影響をうけ
ることがある。However, due to this increase in frequency, electromagnetic wave noise generated by electronic components is radiated from openings and closing parts, joints, etc. of the housing that houses each electronic component, and gets onto surrounding signal lines, or It may act directly on electronic components, causing problems such as failure or malfunction of the electronic components. Furthermore, since magnetic recording elements of electronic components are made by magnetizing a magnetic material at high density with small magnetic energy, they may be adversely affected by external magnetic fields such as electromagnets, such as loss of recorded information.

Electromagnetic shielding gasket made of highly conductive metal (
An electromagnetic wave shielding gasket (hereinafter referred to as an elastomer gasket) made of an elastomer containing highly conductive metal particles or carbon black particles (hereinafter referred to as a metal force socket) is loaded into the gap in the housing.
［発明が解決しようとする課題］
しかしながら、上記のような金属又はエラストマ自身ケ

のような問題点が残されている。[Problems to be Solved by the Invention] However, even if the metal or elastomer itself is used as described above, shielding of electromagnetic waves is still insufficient, and the following problems remain.

とされるが、金属性ガスケットでは弾性変形が生じない
ために、筐体の気密及び水密を保つことが難しい。In other words, the airtightness and watertightness of the five bodies that house electronic components may vary depending on the environment in which the various devices using the electronic components are used, such as a high humidity atmosphere in a washing machine or outdoors in a car. required. In other words, the electromagnetic shielding gasket has good conductivity and low electrical resistivity to suitably shield electromagnetic noise, and elasticity to be loaded into the gap in the housing to keep it airtight and watertight. However, since a metal gasket does not undergo elastic deformation, it is difficult to maintain airtightness and watertightness of the housing.

ノイズのシールドには不十分である。However, while the electrical resistivity decreases as the content of conductive particles increases, it is known that when the content of conductive particles exceeds a predetermined value, the elasticity of the elastomer itself is impaired. Therefore, the content of conductive particles is limited to a certain upper limit. However, even if the conductive particles are set to such a limit value, it is insufficient to shield electromagnetic noise in the gap between the casings.

Since the aluminum layer 17 is vapor-deposited on the surface of the silicone rubber main body 15 instead of containing conductive particles as in the conventional case, the elasticity of the silicone rubber itself is not impaired. Therefore, when the case attachment body 5 is closed, moisture and air from the outside i3 can be reliably blocked and the case 3 can be kept sufficiently airtight and watertight.
またこの電磁波シールド用ガスケット１の断面は、四角
