The present invention is to obtain a Ti-Zn-Mn-V-Fe based hydrogen storage alloy having the excellent hydrogen absorbing and discharging performance at a low cost. An alloy represented by the general formula: Ti1-xZrxMnw-y-zVyFez (wherein 0<=x<=0.5, 0<y<=0.6, 0<z<=0.2, and 1.8<=w<=2.2) is produced using a ferrovanadium (alloy of a V and an Fe) as one of the raw materials. The oxygen content of the alloy is limited to 5,000 ppm or less. A hydrogen storage alloy having the excellent hydrogen absorbing and discharging performance can be produced using an inexpensive ferrovanadium. Furthermore, an impurity oxygen, which adversely effect the performance, can be limited easily.
