In this paper, we explain new EM(electromagnetic) wave absorber that mixed NC(Natural Ceramics) and Ferrite with NL(Natural Lacquer). At first, a mixed NC and Ferrite(NC : F = (0.1~30)wt% : (99.9~70)wt%) burn at 950˚~1250˚C. And then, it is comminuted and injected into NL((NC+F) : NL = (30~80)wt% : (70~20)wt%), finally we made Ferrite-NL EM wave absorber. Generally, conventional labor Ferrite covers only 500 MHz to 10 GHz under tolerance limits of 2 to 6 dB in absorption, and Ferrite-NL is over 8~14 dB. However, NCFerrite-NL has superior absorption ability. It is over 16 ro 19 dB through 500 MHz to 10 GHz.
