The objective of the present invention is to provide an electroconductive paste for forming a solar cell electrode, said paste yielding excellent electrical characteristics and adhesion to a substrate to a more satisfactory degree of strength. The electroconductive paste for forming a solar cell electrode contains a tellurium-based glass fillet, an electroconductive powder, and an organic vehicle. Said fillet contains 30-70 mol% of tellurium, 15-40 mol% of tungsten, 5-30 mol% of zinc, 0-20 mol% of boron, and 0-10 mol% of zirconium (where the total boron and zirconium content is greater than 0 mol%), said amounts being expressed in terms of oxides. The electroconductive powder has silver as a main component and a specific surface area of 0.4 m 2 /g or more. |
