To provide a nonaqueous electrolytic storage element, which contains: a positive electrode, which contains a positive electrode material layer including a positive electrode active material capable of reversibly accumulating and releasing anions; a negative electrode, which contains a negative electrode material layer including a negative electrode active material capable of reversibly accumulating and releasing cations; a separator provided between the positive electrode and the negative electrode; and a nonaqueous electrolyte containing an electrolyte salt, wherein a pore volume of the negative electrode material layer per unit area of the negative electrode is larger than a pore volume of the positive electrode material layer per unit area of the positive electrode. |
