PURPOSE: To reduce the thickness and weight of a radio wave absorbing wall structure for reducing the load exerted on a structure driver by employing a reflector of the radio wave absorption structure part superimposed on a reinforced concrete structure part also as a structure reinforcing part.

CONSTITUTION: A stainless part or a welded wire mesh which is coated with resin over its surface, both serving as a reflector 13 of a radio wave absorption structure part A is set at a predetermined position from a radio wave absorber 12. The reflector 13 serves as a structure reinforcing part and constitutes a reinforcing concrete structure part 13 together with a structure reinforcing part 14 located on the upper end of a concrete 15. Hereby, the thickness and weight of the radio wave absorbing wall structure are reduced to reduce the load exerted on a structure driver.
