1. Field of the Invention
The present invention relates to a component material for constructing a casing for various kinds of electronic devices.
2. Description of the Related Art
For a casing for various kinds of electronic devices, such as a camera, a mobile phone, a PDA (Personal Digital Assistant), a personal computer, and so on, use has conventionally been made of materials such as metal (aluminum, stainless steel, titanium and magnesium) or a resin (acrylonitrile-butadiene-styrene (ABS) resin, polycarbonate, acrylic resin). These materials have been adopted not only from the functional consideration such as their moldability, rigidity and corrosion resistance, but also for aesthetics.
Recently, further attention has also been paid to using, as a familiar, and environment-friendly material, wood or a woody material obtained by processed wood. For example, Jpn. Pat. Appln. KOKOKU Publication No. 7-24353 discloses an electromagnetic shielding material obtained through impregnation of wood or woody material with phenol resin and subsequent carbonization. The Publication discloses the idea of, while using the wood material, imparting an electromagnetic shielding property to a product obtained.
