A wood decorative material coated with resin composite film, comprising a laminate of, arranged in the following order, a wood substrate; a heat bonding layer (A) formed from a heat bonding resin composition comprising 100 parts by weight of a thermoplastic resin (a-1) and 0.001 to 80 parts by weight of a tackifier resin (a-2), the above heat bonding resin composition having a melting point or softening temperature of 170&deg; C. or below and exhibiting a melt flow rate (MFR) at 190&deg; C. of 1 to 500 g/10 min; and a mar-proof surface layer (B). Not only can beautiful appearance be obtained while retaining natural texture without the application of lacquer but also surface protection and bending working properties are improved.
