AUTOMOBILE COMPONENT

WIPO Patent Application WO/2019/186970

A1

Provided is an automobile component, the sound absorbing performance of which can be improved by attenuation due to vibration of a thin film, while weight reduction of the automobile component is achieved. The automobile component according to the present invention is provided with: a core layer (10) in which tubular cells (20) are arranged in a plurality of lines; and a nonwoven fabric layer (30) disposed on one surface or both surfaces of the core layer. Cell ends on the one surface of the core layer include closed surfaces (21) and open ends (22) in every other line, and cell ends on the other surface of the core layer include the open ends (22) in the lines in which the cell ends on the one surface include the closed surfaces, and include the closed surfaces (21) in the lines in which the cell ends on the one surface include the open ends. The inner spaces of the cells (20) are connected to the outside through the open ends (22). A thin resin film layer (40) including a plurality of open holes is provided between the core layer and the nonwoven fabric layer. When the ratio of the area of an open surface formed by each of the open ends and the area of the open hole provided in the resin film layer so as to correspond to the open surface is defined as S, 0
