Abstract
A conductive composition has excellent adhesiveness and conductivity. A conductive composition contains copper powder, cuprous oxide, a lead-free glass frit, and an acid-based additive. The lead-free glass frit is contained in an amount of 9 to 50 parts by mass relative to 100 parts of the copper powder. The lead-free glass frit contains a borosilicate zinc-based glass frit and a vanadium zinc-based glass frit. The borosilicate zinc-based glass frit contains boron oxide, silicon oxide, zinc oxide, and optional other components, among which boron oxide, silicon oxide, and zinc oxide serve as top-three oxide components in terms of content. The vanadium zinc-based glass frit contains vanadium oxide, zinc oxide, and optional other components, among which vanadium oxide and zinc oxide serve as top-two oxide components in terms of content. The acid-based additive is contained 0.1 to 5.0 parts by mass relative to 100 parts of the copper powder.
