Abstract:
    The inention relates to a radio wave absorber which can achieve low cost, a small transportation volume, an excellent radio wave absorbing characteristic from a low frequency to a high frequency with a short length, a small or no difference in the characteristic of a polarization plane, and can be easily fabricated and worked. In a radio wave absorber (10), four hollow tetrahedrons (20) each of which has one open surface are connected such that a surface (20a) opposed to the open surface of the hollow tetrahedron (20) forms a side of a hollow pyramid (22). The radio wave absorber (10) is composed of a radio wave absorbing member shaped like a thin plate. The radio wave absorbing member shaped like a thin plate preferably has a corrugated cardboard structure in which at least one sheet contains a conductive material.
