Abstract:

To provide an electric wave absorber which can be manufactured without positive addition of a carbon source and to provide its manufacturing method.

The electric wave absorber is obtained by laminating a dielectric layer made of a ceramic-carbon composite and attenuating electromagnetic energy on a surface of an electric wave reflecting material layer reflecting coming electric wave. The manufacturing method of the electric wave absorber includes a process of forming the ceramic-carbon composite using a carbonization decomposition reaction of an organic substance and a process of laminating the ceramic-carbon composite on the surface of the electric wave reflecting layer.
