PROBLEM TO BE SOLVED: To provide a timber and thermoplastic resin composite material for coating of a woodgrain pattern having convenience capable of obtaining a color, a gloss and a sense of a peculiar ruggedness on a woody surface similar to those of a woodgrain of a natural tree merely by executing a simple coating work and coating a favorite color by a user and to provide a method for forming the woodgrain pattern similar to the woodgrain of the natural tree. SOLUTION: The method for forming the timber and thermoplastic resin composite material for coating of the woodgrain pattern comprises a first grinding step of forming many woodgrain-like ground grooves 7 on a surface of a molding 1 of the timber and thermoplastic resin composite material by using a grinding sheet on which abrasive grains of a grain size of 24 to 60 are fixed, then a second grinding step of grinding vertex parts 8 of rising strips between the many grooves formed in the previous step by a grinding sheet in which abrasive grains of a grain size of 100 to 400 are fixed, and then a step of removing fluffing of the vertex parts by using a metal brush, buffing or the both to form a polished surface in which absorption of a paint is suppressed to form the timber and thermoplastic resin composite material in which fluffing 10 is retained in a depth (p) of each of the deep grooves 7.
