Abstract: The present invention provides a photoelectric conversion element having a high power generation efficiency, raising no problem of corrosion, and being applicable to a substrate having a low heat resistance, as well as a method of producing the same. It is a photoelectric conversion element formed in such a manner that a reference electrode serving as a negative electrode and a counter electrode serving as a positive electrode are arranged to oppose each other.
