 A surface-decorated article by noble metal having a decorating matter of noble metal fused to the surface of a ceramic article. The decorating matter has a dual layer structure of a frit layer and an insulating noble metal film layer, which film layer comprising golden components of 60-90% Au, 3-15% Si, 2-11% In and 2-14% Ca. The noble metal decorating matter is not damaged on exposure to an electronic range, superior in chemical stability and abrasion resistance.
