An electrode active material for a power storage device of the invention indudes a ketone compound that indudes a ring structure in a molecule, the ring structure being a five-membered or seven-membered ring composed of atoms at least three adjacent ones of which are each bonded to a ketone group. The electrode active material for a power storage device of the invention has a high weight-energy density and good reversibility of oxidation-reduction reaction. The use of the electrode active material for a power storage device of the invention can provide a power storage device having a high capacity, a high voltage, and good charge/discharge cycle characteristics.
