PURPOSE: To improve radio wave absorbing capacity by integrally stratifying and joining a ferrite molded form onto the surface of a body.
CONSTITUTION: Ferrite molded forms 2 are held among flanges and webs for adjacent holding materials 1 molded to a T-shaped section while the holding materials 1 are fixed to body concrete 4 in the rear through anchors 3 mounted to the holding materials 1. Consequently, the ferrite molded forms 2 are stratified and joined integrally onto the surface of the body concrete 4, thus constituting a radio wave absorbing wall. That is, the molded forms 2 are superposed onto the surface of the body concrete 4 through the holding materials 1 and the anchors 3 without boring anchor bolt through-holes to the body concrete 4 to the ferrite molded forms 2. Accordingly, radio wave absorbing performance is not deteriorated, and the radio wave absorbing performance of the ferrite molded forms 2 is not inhibited because the holding materials 1 are made of a nonmetal.
