In an electrode substrate, the surface of a metal circuit layeris covered and insulated by an insulating layer. In a photoelectric conversion element that uses this electrode substrate, the metal circuit layer is reliably shielded from an electrolyte solution or the like so that corrosion and leak current thereof is effectively prevented, and the photoelectric conversion efficiency can be improved. The insulating layeris preferably made of a material that contains a glass component, and is particularly preferably formed by printing a paste that contains glass frit. The metal circuit layeris preferably formed using a printing method.
