To provide a mounting structure of a radio wave absorber in a radio wave darkroom that avoids excessive force acting on a junction between a shield member and the radio wave absorber caused by an earthquake, and prevents the radio wave absorber from falling off.SOLUTION: In a shield wall 1 using a sliding method, a radio wave absorber 6 is attached to a shield member 2 by means of a free fitting joint 8 through a transverse reinforcement material 7b. The free fitting joint 8 includes a first free fitting joint 8a and a second free fitting joint 8b. The first free fitting joint 8a is a T-shaped cross-section member attached to the transverse reinforcement material 7b. The second free fitting joint 8b are slits formed in the upper and lower surfaces of a base 6a of the radio wave absorber 6. To attach the radio wave absorber 6 to the shield member 2, one end (header) of the T-shaped cross-section members 8a, 8a is aligned with one end of the slits 8b, 8b, respectively the radio wave absorber 6 is inserted horizontally to complete fitting.SELECTED DRAWING: Figure 3 【課題】電波暗室において、地震によって生じるシールド部材と電波吸収体との接合部に作用する過度な力を避け、電波吸収体の脱落を防止する電波吸収体の取付け構造を提供する。【解決手段】スライド工法によるシールド壁面1において、電波吸収体6はシールド部材2に横補強材７bを介し、遊嵌接合部8によって取付ける。遊嵌接合部8は第一遊嵌接合部8aと第二遊嵌接合部8bを備え、第一遊嵌接合部8aは横補強材7bに取付けられたＴ形断面部材である。第二遊嵌接合部8bは電波吸収体6の台座部6aの上下面に形成されたスリット部である。電波吸収体6をシールド部材2に取付けるには、Ｔ形断面部材8a,8aの片端部（小口）に、スリット部8b,8bの片端部をそれぞれ合わせ、水平方向に電波吸収体6を挿入して篏合を完了する。【選択図】図３
