Abstract
A broad-band radio wave absorber with a plurality of pieces of a magnetic member disposed parallel to each other or in a crosswise way on a reflecting plate. Each of the pieces of the magnetic member is configured in such a manner that its thickness is arranged so as to become smaller from its bottom toward its top in a stepwise fashion and that so as to be longer than its bottom thickness. Further, each of the pieces of the magnetic member is disposed in a relationship spaced away from the adjacent pieces thereof in such a predetermined distance longer than the bottom thickness of each piece thereof.
