PROBLEM TO BE SOLVED: To improve sound absorption performance, with a simple structure.SOLUTION: A sound absorption structure (1) comprises: a rear side surface member (21) having length in a predetermined direction; a front side surface member (22) having length along the predetermined direction which is shorter than that of the rear side surface member (21); and a sound absorber (3). The front side surface member (22) is arranged in parallel to the rear side surface member (21) and forward separated from the rear side surface member (21). The sound absorber (3) is disposed on a first area (24) exposed from an opening (23) which is a front side of the rear side surface member (21) and is adjacent to the front side surface member (22) in the predetermined direction, and extends to a second area (25) sandwiched by the front side surface member (22) and the rear side surface member (21).SELECTED DRAWING: Figure 1
【課題】簡易な構造で、吸音性能を向上させること。【解決手段】吸音構造（１）は、所定方向に長さを有する後方面部材（２１）と、所定方向に沿う長さが後方面部材（２１）よりも短い前方面部材（２２）と、吸音材（３）とを備えている。前方面部材（２２）は、後方面部材（２１）と平行かつ後方面部材（２１）から前方に離れて配置されている。吸音材（３）は、後方面部材（２１）の前方であって前方面部材（２２）と所定方向に隣接して位置する開口部（２３）から露出する第１領域（２４）に設けられており、かつ、前方面部材（２２）と後方面部材（２１）とに挟まれる第２領域（２５）にまで延在している。【選択図】図１
