PROBLEM TO BE SOLVED: To enable many ions to contribute charging/discharging by increasing the amount of electrolytic solution even in a battery cell having a limited volume.SOLUTION: In a secondary battery, an anode, an electrolytic solution for the anode, a separator, an electrolytic solution for a cathode, and the cathode are provided in this order, and the separator is made of a solid electrolyte which transmits only ions of an anode metal. At least the cathode is formed of a metal porous body of a three-dimensional network structure. Since the electrolytic solution can be stored even in pores, the amount of ions contributing to charging/discharging can be increased. |
