<P>PROBLEM TO BE SOLVED: To provide a radio wave absorbent capable of uniformly attaining a dielectric loss with high accuracy to a high frequency, having excellent workability and capable of being easily formed in a complicated shape, lightweight, superior even in an environment, capable of being preferably used for a box body or the like for electronic equipment, capable of uniformly attaining the dielectric loss with the high accuracy to the high frequency such a radio wave as particularly 2 to 80 GHz, being easily manufactured having high versatility and proper to an industrial manufacturing. <P>SOLUTION: In the radio wave absorbent containing a thermoplastic resin and a carbon component, the content of the carbon component ranges from 30 to 80 mass%. In the radio wave absorbent, the average particle diameter of the carbon component ranges from 15 μm to 1 mm, preferably the carbon component is composed of graphite, the carbon component has a thickness at 0.01 to 1 times to the wavelength of an absorption radio wave, and the frequency of the absorption radio wave ranges from 2 to 80 GHz. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
