A polycyclic aromatic compound where sulfur is bonded and nitrogen is not included in a cyclic structure is used for the electrode active material. The polycyclic aromatic compound has a polyacene structure where sulfur is bonded, and an intensity ratio D/G of a D-peak to a G-peak of a graphite structure in a Raman spectrum shows 0.2 to less than 1.0. The sum total of the contents of carbon and sulfur is 85 wt.% or more in the polycyclic aromatic compound. Capacity of the power storage device is considerably improved since electrostatic capacity is superimposed in the polycyclic aromatic compound in addition to the capacity accompanying oxidation and reduction of the sulfur.
