Abstract

PURPOSE: To provide the title shielding member having resiliency to keep suffi cient air tightness and water tightness as well as high electromagnetic wave shielding capability by forming a member body with resin including elastoma and depositing a conductive film on a body surface.
CONSTITUTION: A conductive film is formed on the surface of a body compris ing, as a raw material, resin such as elastomar as an electromagnetic wave shielding member. For materials of the conductive film there are available metals such as aluminum, titanium, and nickel or copper. Once the electromag netic wave shielding member is applied to spacings in a casing and to portions where a plurality of members such as opening/closing parts make contact with each other, they make close contact with those members so as to prevent any spacing from being formed, by making use of flexibility of the resin-made body, for the purpose of securing air and water tightnesses. Hereby, surface resistivity along the body surface is lowered to satisfactorily shield any electromagnetic wave propagating through the members.
