Abstract
A process for producing a substrate for mounting element includes forming a thick conductor layer-provided substrate having a thick conductor layer made of a metal composed mainly of silver (Ag) or copper (Cu), on a surface of an inorganic insulating substrate made of an inorganic insulating material, applying wet blast treatment to the thick conductor layer to planarize the surface of the thick conductor layer to a surface roughness Ra of at most 0.02 μm, and forming a nickel (Ni)/gold (Au)-plated layer on the thick conductor layer having the surface planarized by the wet blast treatment.
