A quinone derivative is represented by general formula (1), (2), or (3). In general formulae (1), (2), and (3), R1, R2, R3, R4, R11, R12, R13, R14, R21, R22, R23, and R24 each represent, independently of one another, a hydrogen atom, a cyano group, a halogen atom, an optionally substituted alkyl group having a carbon number of 1-6, or an optionally substituted alkoxy group having a carbon number of 1-6. R5, R6, R15, R16, R25, and R26 each represent, independently of one another, an optionally substituted alkyl group having a carbon number of 1-6, an optionally substituted alkoxy group having a carbon number of 1-6, an optionally substituted aryl group having a carbon number of 6-14, an optionally substituted aralkyl group having a carbon number of 7-12, or an optionally substituted cycloalkyl group having a carbon number of 3-10.
