    • This invention relates to a composition for preparing a nonflammable, light-weight radio wave absorber which has a capacity of absorbing radio waves at low frequency bands of 30 MHz to 1,000 MHz or at high frequency bands of over 1,000 MHz, a radio wave absorber member using the above composition, a radio wave absorber using the radio wave absorber member, and a method for producing the above wave absorber member.
      The radio wave absorber composition for a low frequency band of 30 MHz to 1,000 MHz mainly consists of cement, light-weight aggregates, non-conductive fibers and synthetic resin emulsion. And, the wave absorber composition for a high frequency band of over 1,000 MHz mainly consists of cement, light-weight aggregates, carbon fibers and/or carbon graphite and synthetic resin emulsion.
