Although the influence on the plateau property of the y value differed somewhat depending on the content of u, no major difference was observed. Therefore, y was set in the range of 0.90 to 1.05.

数比でｏ、ｏｉ以上必要である。The hydrogen dissociation equilibrium pressure can be lowered to about 115 when Cu is not added by adding Cu in an atomic ratio of about 0.1. In order to rapidly absorb hydrogen at a hydrogen pressure of 10 kg/e or less at around room temperature, it is necessary that the hydrogen storage region pressure of the alloy is less than 1 Ottg/c. For this reason, the amount of Cu added needs to be at least o, oi in terms of atomic ratio relative to (Fe+Cu).

In order to obtain a hydrogen release pressure of about 5 kg/cd at an easily obtainable temperature of 80° C. or lower, the amount of Cu added is desirably 0.1 or less in terms of atomic ratio with respect to (Fe→Cu).
