Abstract
A conductive paste includes a conductive powder containing at least one of copper and nickel as a main component, a glass frit, and an organic vehicle, wherein the glass frit is a tellurium-based glass frit that essentially does not contain any lead component and contains tellurium as a network former in an amount of 35 to 70 mol % in terms of oxide, the tellurium-based glass frit containing silver as an essential component. The above conductive paste can provide favorable characteristics and favorably be used in the formation of light-receiving surface electrodes of a solar cell element even when the conductive paste includes one or more of copper and nickel as its conductive component.
