Abstract: A hydrogen-absorbing alloy included in alloy powder for electrodes includes elements L, elements M, Ni, Co, and elements E. L include La as an essential component. L do not include Nd, or, even when L include Nd, the percentage of Nd in L is 5 mass % or less. Furthermore, M include at least Mg, E include at least Mn, and molar ratio α1 of Mg to the sum total of L and M satisfies 0.000
