Abstract
In an electric power generating element, either positive or negative electrode includes a composition containing an organic compound as a main agent and the positive electrode has an electrically conductive substance so that relatively low-temperature thermal energy is efficiently converted to electric energy. Polyethylene glycol is employed as the organic compound and graphite or a graphite composition is employed as the conductive substance. Salt providing ionic conductivity may be added to the organic compound or polyethylene glycol, and the negative electrode may be formed of a metal having an ionization tendency as large as or larger than copper or a composition of the metal.
