摘要： There are provided an electric power generating element which has excellent cycle characteristics and which can be produced in satisfactory yield, and a nonaqueous electrolyte battery including the electric power generating element. In an electric power generating element including a positive electrode layer, a negative electrode layer, and a solid electrolyte layer arranged between these electrode layers, the solid electrolyte layer containing Li, P, S, and O, the O content of the solid electrolyte layer is set so as to be reduced stepwise or continuously from the positive electrode layer side to the negative electrode layer side. When the electric power generating elements each having the structure are produced, most of them provide stable cycle characteristics, i.e., the electric power generating elements are produced in satisfactory yield
