While reducing an increase in the cost of an on-vehicle battery for use in an on-vehicle power supply device, the on-vehicle battery is reduced in size and weight. An on-vehicle battery 11 includes a lead storage battery 13 and a second storage battery 14. The second storage battery 14 is connected in parallel with the lead storage battery 13. The second storage battery 14 has a positive electrode and a negative electrode. The positive electrode includes, as a positive electrode active material, a spinel-type lithium-nickel-manganese oxide. The negative electrode includes, as a negative electrode active material, at least one of graphite, soft carbon, hard carbon, and an alloy-based material containing an Si element.
