To provide a sound absorber for a vehicle interior that can suppress deterioration in design while improving quietness in a vehicle interior.SOLUTION: Sound absorbers (7), which are arranged in inner walls (3, 5) in a vehicle interior (1) of a vehicle, comprise containers (11, 17) forming contours of the sound absorbers and sound absorbing materials (13) included in the containers. At an inner side of the vehicle interior of the container is provided with a wall (17) with open holes in which a plurality of open holes (21, 121, 122, 223) are formed, where some of the open holes are formed to extend obliquely at a predetermined angle with respect to a normal direction of a surface (17c) inside the vehicle interior of the wall with open holes.SELECTED DRAWING: Figure 3

    【課題】車室内の静寂性を向上しつつ、意匠性の低下を抑制することができる車室内用吸音器を提供する。【解決手段】車両の車室内(1)の内壁(3,5)に配設される吸音器(7)であって、吸音器の外郭を形成する容器(11、17)と、容器に内包される吸音材(13)と、を備え、容器の車室内側には、複数の開孔(21,121,122,223)が形成された開孔壁(17)を有しており、各開孔の少なくとも一部は、開孔壁の車室内側の面(17c)の法線方向に対し所定角度傾斜して延びるように形成される。【選択図】図3
