PURPOSE: To obtain a radio wave absorbing body which is extremely light, is superb in retaining configuration, and is superb in heat resistance as well as mechanical strength by constituting a radio wave absorbing body by a radio wave absorbing material with polyolefin resin expansion molding as a core material.
CONSTITUTION: A radio wave absorbing material such as a plastic rubber including a large quantity of Mn-Zn magnetic material, carbon black, or polarity base is dispersed to acryl emulsion to create a dispersion. A thick plate 1 of expansion molding body of polyolefin resin etc., is sliced to create a thin plate 2 and to form a thin and long plate 3 in isosceles triangle shape. Then, a hollow pyramid core material 4 is created. A mounting member 5 is conjugated to the bottom side and dispersion is applied to it. The obtained radio wave absorption body configuration object is extremely light, is superb in mechanical strength, and can be easily installed.
