Zusammenfassung:A battery including a plurality of unit electrode bodies, each having a positive electrode including a molded body of a positive electrode mixture, a negative electrode including a negative electrode active material layer, and a solid electrolyte layer or a separator interposed between the positive electrode and the negative electrode. The plurality of unit electrode bodies is stacked on top of each other. Adjacent ones of the unit electrode bodies are connected with each other in series. L/S≤0.5 and 0.02≤L≤0.20, where L (cm) is the thickness of each unit electrode body, and S (cm2) is the electrode area of the unit electrode body. The molded body of the positive electrode mixture and the negative electrode active material layer each have a porosity of 10% or less. When the solid electrolyte layer is included, the solid electrolyte layer has a porosity of 10% or less.
