PURPOSE: A substrate for mounting element and a manufacturing method thereof are provided to obtain a substrate for mounting a device having excellent sulfur-resistance. CONSTITUTION: In a substrate for mounting element and a manufacturing method thereof, an inorganic insulating substrate(1) is comprised of an inorganic insulating material. A thick film conductive film is formed on the surface of the inorganic insulating substrate and is comprised of a metal of Ag or Cu which is used as a main component. A conductive metal plating layer(2) is formed on the thick film conductive layer. The thick film conductive layer has a surface which is planarized through a wet-blast process and has the intensity of illumination under 0.02um. |
