PURPOSE: To emphasize a color by an inorganic coat by forming a conductive film on a transparent coating film provided on a colored layer on a substrate besides, forming a pattern of a thick metal plating layer and forming the inorganic coat on the thick metal plating layer with the aid of a vapor phase method.

CONSTITUTION: When the inorganic coat 6 is made by two or more layers and coloring is executed by using the interference of the light thereof, they are laminated by the respective combination of Cr - SiOz or the like. For exam ple, when the inorganic coat 6 consisting of three layers of Cr - Cr2O3 - Cr is formed by resistance heating, a color is produced by the first layer Cr and the second layer Cr2O3 and the protecting colaration of the coat is adjusted by the third layer Cr. When they are combined by changing the thickness of the respective layers, a color tone having various metallic luster can be pro duced. On a dial plate, the pattern is swollen and the surface thereof is colored by the color of the inorganic coat 6 or a color by the interference thereof, besides.
