To provide a compact, thin wave absorber that does not employ heavy metal for materials of the wave absorber layer and makes effective use of carbon nanotube structure properties to absorb a wide band of radiowaves, and to provide a method for manufacturing the wave absorber.
The wave absorber comprises a wave absorber and a method for manufacturing the absorber. In this wave absorber, uniform wave absorber layers 2 contain carbon nanotube structures constituting a mesh structure made of multiple carbon nanotubes and bridges formed by chemical bonding of multiple functional groups connecting at least either end of each carbon nanotube to one of the other nanotubes, and are arranged on the surface of a base substrate 1 like tiles.
