The vehicle interior material according to the present application has a laminated structure of n layers (n is a natural number of 2 or more), and includes at least a base material as a first layer and a skin layer as an nth layer. The vehicle interior material is configured so that the following formula (1) is satisfied, where dn (mm) is the thickness of each of the n layers, En (GPa) is the Young's modulus, and rho (g/cm < 3 >) is the density of the entire vehicle interior material. In addition, a seat back plate according to the present application is formed using the vehicle interior material.
