To provide a radio wave absorber and an aircraft intake duct that has a simple structure, is lightweight, and can widen a radio wave absorption band.SOLUTION: In a radio wave absorber 1, an internal space S is formed by being partitioned from an outside by a radio wave absorbing plate 2, such that a radio wave r incident in the internal space S propagates in the internal space S while being partially absorbed and reflected by the radio wave absorbing plate 2, and a plurality of types of radio wave absorbing plates 2 having different central frequencies f0 in an absorption band of the radio wave r is arranged side by side in a propagation direction of the radio wave r and a direction orthogonal to the propagation direction of the radio wave r.SELECTED DRAWING: Figure 1

    【課題】簡素な構造で、軽量であり、かつ、電波の吸収帯域を広帯域化することが可能な電波吸収体及び航空機のインテークダクトを提供する。【解決手段】電波吸収体1は、電波吸収板2により外部から区画されて内部空間Sが形成されており、内部空間S内に入射した電波rが電波吸収板2により一部吸収されつつ反射されながら内部空間S内を伝播するように構成されており、電波rの吸収帯域の中心周波数f0が互いに異なる複数種類の電波吸収板2が電波rの伝播方向や電波rの伝播方向に直交する方向に並設されて形成されている。【選択図】図1
