摘要：
A hydrogen storage alloy containing a phase of a chemical composition defined by a general formula A5·xB1+xC24: wherein in the general formula A5·xB1+xC24, A denotes one or more element(s) selected from rare earth elements; B denotes one or more element(s) selected from a group consisting of Mg, Ca, Sr, and Ba; C denotes one or more element(s) selected from a group consisting of Ni, Co, Mn, Al, Cr, Fe, Cu, Zn, Si, Sn, V, Nb, Ta, Ti, Zr, and Hf; and x denotes a numeral in a range from −0.1 to 0.8: and the phase has a crystal structure belonging to a space group of R-3m and having a length ratio of the c-axis to the a-axis of the lattice constant in a range of 11.5 to 12.5.
