Abstract

PURPOSE:To maintain excellent appearance for a long time, by a method wherein, when a design in a figure is formed on a side wall part, a smooth part and a coarse part respectively having given central line average coarseness are formed in a manner that the smooth part is dented, and expression is made by means of a difference in surface coarseness. CONSTITUTION:When a design 1 is formed on a side wall part, it is formed with a smooth part S and a coarse surface part R, and the smooth part S is dented to a level lower than that of the coarse surface part R. In this case, a dent amount is set to at least 1mm. Central line average coarseness of the smooth part S is set to 1.6a, and central line average coarseness of the coarse surface part R is set to 3.2a-25a. This constitution enables maintenance of excellent appearance of a design part for a long time.
