There is provided an automobile component capable of improving sound absorption performance by damping due to vibration of a thin film as well as reducing weight of the automobile component. An automobile component of the present invention includes a core layerin which tubular cellsare arranged in a plurality of rows, and a nonwoven fabric layeron one or both surfaces of the core layer. The cells have closed surfacesand open endsin every other row as cell ends on one surface of the core layer. As cell ends on the other surface of the core layer, the cells have open endsin the rows where the cells have the closed surfaces as cell ends on the one surface, and have closed surfacesin the rows where the cells have the open ends as cell ends on the one surface. The open endsallow the internal space of the cellsto be in communication with the outside. A thin resin film layerhaving a plurality of apertures is provided between the core layer and the nonwoven fabric layer. A ratio S is set so that 0<S<0.3, where S represents a ratio of an area of the apertures provided in the resin film layer corresponding to an opening defined by the open end to an area of the opening.
