As shown in FIG. 8, the metal substrate 1 is subjected to sand shot processing to form a sand shot surface (8) which sinks from the surface of the metal substrate 1 shown in FIG. 9 and has a smooth, metallic luster. Next, the resin coating (2;
8) is finished so smoothly that it has at least a semi-gloss, so it is resistant to stains and is easy to clean, making it possible to maintain its beautiful appearance with less effort. Furthermore, since the resin coating (2) during etching is used as a masking during sand shot processing, the processing steps can be simplified and manufacturing can be done at low cost. By changing the particle size of the sandshot particles, various sandshot finishing surfaces (8) can be obtained and decorative surfaces can be diversified. Furthermore, by subjecting the metal substrate to a treatment for forming a colored oxide film before and after sand shot processing, it is possible to produce a variety of decorative boards with even greater variation.
