PROBLEM TO BE SOLVED : To produce a lightweight and inexpensive multicomponent based AB2 type hydrogen storage alloy capable of dissociating and discharging hydrogen at <=100 deg.C and further capable of repeatedly occluding and discharging the same without causing its conversion into the amorphous or nonuniformed one. SOLUTION : The ternary and the multicomponent based AB2 type hydrogen storage alloys have chemical compositions expressed respectively by the following general formulae and are composed of a Laves phase as the main phase : (Mg1-xCax)Niz, and (Mg1-x-aCaxAa)(Ni1-bBb)z : wherein; A in the above formula is at least one kind of element selected from Ti, Y, Zr, Nb, Ta and rare earth elements; B is at least one kind of element selected from Al, Si, V, Cr, Mn, Fe, Co, Cu and Zn; (x) is prescribed as 0.1<=x<=0.5, (a) as 0
