A charge / discharge characteristic of an electrode using a layered structure as an electrode active material is further improved. An electrode for a power storage device has an organic skeleton layer containing an aromatic dicarboxylate anion, and an alkali metal element layer in which an alkali metal element coordinates to oxygen contained in the carboxylate anion to form a skeleton. The layered structure is included as an electrode active material, and carboxymethylcellulose as the water-soluble polymer is in a range of 1.5% by mass to 3.5% by mass in the whole of the electrode active material, the conductive material, and the water-soluble polymer. Including. In addition, the layered structure is manufactured by a spray drying method, and a peak intensity ratio when an X-ray diffraction measurement is performed on the electrode for a power storage device satisfies a predetermined range.
