A secondary cell in which are stacked pluralities of: positive electrodes (10a, 10b) equipped with an electrolytic solution and an electrode member (2) immersed for use in the electrolytic solution, the electrode member (2) having positive electrode active material layers (12, 13) formed on the surface of a positive electrode current collector foil (11); negative electrodes (20) having negative electrode active material layers (22, 23) formed on the surface of a negative electrode current collector foil (21); and separators (30) disposed between the positive electrodes (10a, 10b) and the negative electrodes (20). Each of the positive electrode active material layers (12, 13) and the negative electrode active material layers (22, 23) that face each other across a separator (30) constitute an electrode pair (41, 42). The electrode pairs (41, 42) comprise first electrode pairs (41) made from a first active material layer provided with a first property, which is relatively high-output and low-capacity, and second electrode pairs (42) made from a second active material layer provided with a second property, which is relatively low-output and high-capacity. |
