Abstract:
A wood powder-containing resin molded article which can be reduced in weight by reducing an amount of thermoplastic resin, and also has excellent mechanical strength, and a method for producing the same are provided. A wood powder-containing resin molded article 1 is made of a thermoplastic resin containing wood powder, and includes a non-foamed layer 2 formed on a surface and a foamed layer 3 formed in an inner portion. The foamed layer 3 includes, in order from a side close to the surface, a first foamed layer 3a, a second foamed layer 3b having cells with a smaller average pore size than those of the first foamed layer 3a, and a third foamed layer 3c having cells with a larger average pore size than those of the first foamed layer 3a. The wood powder-containing resin molded article 1 contains a perfuming component.
