A negative electrode of a nickel-metal hydride storage battery includes an active material layer formed on a conductive substrate and including a hydrogen storage alloy powder and a carbon powder. The carbon powder includes some carbon particles each containing at least one metal selected from a group consisting of Ni, Co, Ca, Fe, Mg, Mn, Ti, and V. Each of the some carbon particles include a particle containing the above metal inside thereof. In this negative electrode, the carbon powder contains a metal therein. Thus, while maintaining excellent gas compatibility carbon material inherently has, the carbon powder has improved conductivity as a conductive agent. Therefore, the use of the negative electrode including a hydrogen storage alloy can provide a nickel-metal hydride storage battery that can prevent an excessive increase in its inner pressure, and has excellent high-current discharge characteristics.
