Abstract
A vehicle interior material is configured such that, when the Shore hardness is denoted as H (Hs), the thickness as d (mm), and the bending stiffness as K (MPa·mm4), an index X=H×K×d2 is set to be less than an upper limit value determined according to required level of sewability for the vehicle interior material. Alternatively, the index X is set to be greater than 3500 and less than 54000. As a result, the vehicle interior material can achieve both the necessary rigidity and ease of sewing.
