Abstract
The present invention is an interior material for a vehicle having a skin layer and a base layer. The skin layer contains an olefin-based thermoplastic elastomer, a polyolefin resin, a polylactic acid resin and a styrene-based thermoplastic elastomer, in amounts of respectively 20% to 70% by weight, 10% to 50% by weight, 5% to 30% by weight and 5% to 30% by weight based on 100% by weight of the total of these. The base layer is preferably a thin layer in which a natural fiber is dispersed in a phase of a thermoplastic resin such as a polyolefin resin, or a polyurethane foam layer.
