Abstract:
A hydrogen absorbing alloy containing at least a rare-earth element, magnesium (Mg), nickel (Ni) and aluminum (Al), having an intensity ratio (IA/IB) of not smaller than 0.6 (where IA represents an intensity of the highest peak in a range of 2θ=30°˜34° in the X-ray diffraction pattern using CuKα-radiation as the X-ray source and IB represents the intensity of the highest peak in a range of 2θ=40°˜44°), and not substantially including La as the rare-earth element.
