Abstract
The disclosed is an electromagnetic wave absorber which is characterized in that ultrathin carbon fibers which show a negative magneto-resistance are contained in the matrix, at a ratio of 0.01-20% by weight based on the total weight. By using a loss material which shows a high electromagnetic waves absorption capability at a small amount, the electromagnetic wave absorber which demonstrates a strong electromagnetic radiation absorption capability without deteriorating the characteristics of the matrix. In addition, this electromagnetic wave absorber has a good formability while being made of a low cost composite material, and is useful as electromagnetic wave absorber for GHz band.
