Abstract: A solar cell element containing: a semiconductor substrate; an antireflection 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 and containing silver as a main component and a tellurium-based glass containing tellurium, tungsten, and bismuth. The solar cell element is manufactured by forming the antireflection film on the one main substrate surface; printing on the antireflection film a conductive paste containing a conductive powder mainly containing silver, a tellurium-based glass frit containing tellurium, tungsten, and bismuth, and an organic vehicle; and disposing the antireflection film in the first region and forming the front surface electrode in the second region, by firing the paste and eliminating the antireflection film positioned under the paste.
