[Solution] An interior material 1 for an automobile according to the present invention includes a laminate 4 made up of a surface layer 2 facing the interior and a ventilation control layer 3 provided with holes, and a cushion layer 5 on the vehicle body side pasted to the laminate 4, wherein the proportion of open hole area in the ventilation control layer 3 is set such that a flow resistance value of the laminate 4 will be at least 1000 Ns/m3 but less than 6000 Ns/m3. The interior material is configured to reliably absorb any noise infiltrating a vehicle. Also, the interior material may include a cushion layer pasted to the laminate 4 via an intermediate sound absorption layer 6 and a sound insulation layer 7, so that noise entering the vehicle from tires through the underside of an automobile can be reduced.
