To prevent transmission of sound from both sides.SOLUTION: A sound absorbing and insulating material 10 comprises: a plurality of first concave parts 12 which are formed so as to open on one surface of the sound absorbing and insulating material 10; and a plurality of second concave parts 14 which are formed so as to open on a surface opposite to the one surface of the sound absorbing and insulating material 10. In the sound absorbing and insulating material 10, a bottom part space S1 is provided between a first connection wall 16 for connecting the adjacent first concave parts 12, 12, and a second bottom wall 14b of the second concave part 14 disposed so as to overlap the first connection wall 16.SELECTED DRAWING: Figure 2

    【課題】両側からの音の透過を防止する。【解決手段】吸遮音材10は、該吸遮音材10の一面に開口するように形成された複数の第1凹部12と、該吸遮音材10の一面と反対面に開口するように形成された複数の第2凹部14とを備えている。吸遮音材10は、隣り合う第1凹部12,12同士を繋ぐ第1連結壁16と、この第1連結壁16に重なるように配置された第2凹部14の第2底壁14bとの間に、底部空間S1が設けられている。【選択図】図2
