The present invention provides an electrode active material for an electricity storage device having a structure represented by the following formula (1). In formula (1), R 1 to R 6 may each independently have a hydrogen atom (except when all of R 1 to R 6 are hydrogen atoms), a halogen atom, and a substituent. It is a good phenyl group, a heterocyclic group which may have a substituent, or a hydrocarbon group having 1 to 4 carbon atoms which may have a substituent. |
