An electromagnetic wave absorber includes a dielectric layer, a divided conductive film layer and an electromagnetic wave reflective layer, wherein a ratio of thickness 'd' and wavelength '&#x3bb;' satisfies a condition of [0.01&#x2266;d/&#x3bb;0.03], weight per unit area of the electromagnetic wave absorber falls within a range of 1000 g/mand 3000 g/m. The divided conductive film layer is configured such that each side's length of conductive films is dimensioned within a range of 0.5 mm and 4.8 mm and arrangement distance between adjoining conductive films is taken within a range of 0.01 mm and 3 mm.

Electromagnetic wave absorber

There is disclosed a composition which is layered in a reflective board to constitute a radio wave absorber. In this composition, an electroconductive titanium oxide is compounded with a substrate. With regard to the substrate, there may be used thermoplastic resin, thermosetting resin, rubber or elastomer.

Radio wave absorber composition

The radio wave absorber of the present invention has a radio wave reflector and at least two radio wave absorbing layers disposed on a surface of the radio wave reflector, the at least two radio wave absorbing layers being formed of a base material and electroconductive titanium oxide mixed with the base material. The radio wave absorbing layers have different blend ratios of the electroconductive titanium oxide so as to make their radio wave absorption property different.
