An electrode active material, having as the main component thereof a mixture of oxamide, and an organic compound containing a rubeanic acid, indicated by general formula, in the structural unit thereof. In the formula, n indicates an integer between 1 and 20, and R1-R4 indicate hydrogen atoms, halogen atoms, or a prescribed substituent group such as a hydroxide group, a C1-3 alkyl group, an amino group, a phenyl group, a cyclohexyl group, or a sulfo group. A positive electrode (4) contains this electrode active material. As a result, the electrode active material, an electrode, and a secondary battery are achieved that have high energy density, high output, and good cycle characteristics whereby there is little decrease in capacitance even after repeated discharge. |
