PROBLEM TO BE SOLVED: To provide a grain pattern painting treatment method suitable for obtaining a natural grain-like texture, and a grain pattern emphasizing grinding member used for the method. ;SOLUTION: This method uses a raw material with an exposed surface including a wood component, and a grinding member 4 which has a projected part 41 projecting toward the exposed surface of the raw material and a retreated part 42 retreating from the exposed surface of the raw material and in which the projected part 41 and the retreated part 42 extend along one direction (x direction). A colored paint is applied to at least a part of the exposed surface of the raw material. Subsequently, the part to which the color pigmented paint has been applied is ground along the one direction (x direction) with the grinding member 4. And then, a transparent film of transparency or translucency is accumulated.;COPYRIGHT: (C)2001,JPO
