In addition, a transparent resin layer or a glass fiber-mixed, transparent resin layer is provided on the small timber piece-dispersed, colored, transparent resin layer, or the small timber piece-dispersed, colored, opaque resin layer is provided on a substrate. Consequently, a beautiful decorative board can be provided in which the side surface of the small timber pieces exposed to the surface of the small timber piece-dispersed, colored opaque resin layer are arranged and disposed parallel with the surface of the decorative board, the figure patterns of the small timber pieces appear on the surface of the decorative board effectively without waste, and the figure patterns are thus emphasized.
