Abstract
A conductive paste for a solar cell element front surface electrode that is used to form a front surface electrode of a solar cell element that is provided with a semiconductor substrate, an antireflective film disposed in a first region on one main surface of the semiconductor substrate, and a front surface electrode disposed in a second region on the one main surface of the semiconductor substrate. The conductive paste contains a conductive powder, a mixed glass frit, and an organic vehicle in which the mixed glass frit contains, in the form of mixture, a tellurium-based glass frit containing tellurium, tungsten, and bismuth as essential components and a lead-bismuth-based glass frit that contains lead and bismuth as essential components and that substantially does not contain tellurium.
