There is provided an automotive interior component including an impact absorber mounted to an interior side of a side wall panel of a vehicle, and the shape and structure of the impact absorber that can undergo buckling deformation and absorb an impact load in a side collision are improved to increase an impact absorbing function. The impact absorber 30 mounted on a back surface of an impact area IA in the automotive interior component (door trim) 10 is formed as a hollow box body having an opening 31 on one side and a bottom surface wall 32 on the other side, and improvement such as providing corner cut portions 34 at four corner portions of the bottom surface wall 32, forming a chamfered portion 333 at a corner portion of a side wall 33, or forming a cam groove portion 334, a triangular rib 36, or an inner surface rib 321 is made to adjust a reaction force in a side collision to increase an impact absorbing function.
