[Object] Various electric wave absorbers for the GHz band have been
developed. However, parameters for obtaining the optimal electric wave
absorption characteristic are only the shape and the content of a
dielectric material or a conductive material, and the degree of freedom
of the parameters has been small. Furthermore, in a recent wireless LAN,
electric wave absorbers that can be used for absorbing potentially
dangerous electric waves in a plurality of bands, for example, in two
frequency bands of 2.45 GHz band and 5.2 GHz band, have also been
desired. [Solving Means ] In a woody electric wave absorber including a
laminated magnetic woody material prepared by bonding facing plates
composed of natural wood or a processed woody material with a magnetic
layer composed of an adhesive containing a ferrite powder therebetween
under pressure, the magnetic layer contains a nonmagnetic stainless steel
powder in an amount in the range of 20 to 80 volume percent relative to
the ferrite powder, the total volume content of the ferrite powder and
the nonmagnetic stainless steel powder in the magnetic layer is in the
range of 10% to 40%, the thickness of the magnetic layer is in the range
of 0.5 to 5.0 mm, and the woody electric wave absorber has an electric
wave absorption characteristic in which the center frequency of the
electric waves absorbed lies in the range of 1 to 8 GHz and the amount of
electric wave absorption is 10 dB or more in a 2.45 GHz frequency band or
a 5.2 GHz frequency band.
