A wave absorber of the present invention includes a sequentially laminated structure including an conductor layer ( 11 ) made of a conductive material; a first dielectric layer (polycarbonate substrate ( 12 ) and bismaleimide-triazine substrate ( 13 )) made of one layer or a multilayer of a dielectric material; and a patterned layer ( 14 ) including a plurality of a pattern made of the conductive material, wherein the conductor layer, the first dielectric layer, and the patterned layer are laminated sequentially, and each pattern in the patterned layer ( 14 ) is different from other adjacent patterns with respect to at least one of size and shape. Therefore, the wave absorber has sufficient reflection-attenuating capability to prevent communication failure caused by a reflection of a radio wave and so on, can be thin-sized and reduced in weight, and has a wide-band attenuation property.
