摘要：
Provided is a hydrogen absorbing alloy superior to the MmNi 5 system hydrogen absorbing alloy and the TiFe system hydrogen absorbing alloy that are widely put to practical use in both the capacity density per unit volume and the capacity density per unit weight. The hydrogen absorbing alloy of the present invention is also superior to the conventional TiMn 2 system hydrogen absorbing alloy in the initial activation. The hydrogen absorbing alloy of the present invention is represented by a general formula AM x , where A is at least one element selected from IA group, IIA group, IIIB group, and IVB group of the periodic table, and M is at least one element selected from VB group, VIB group, VIIB group, VIIIB group, IB group, IIB group, IIIA group, IVA group and VA group of the periodic table, x meets the relationship of 2.7
