A hydrogen-absorbing alloy for an alkaline storage battery with high power characteristics and excellent output power stability and a method for manufacturing the same are provided. The hydrogen-absorbing alloy for an alkaline storage battery of the invention is represented by ABn (A : LaxReyMg1-x-y, B : Nin-zTz, Re : at least one element selected from rare earth elements including Y (other than La), T : at least one element selected from Co, Mn, Zn, and Al, and z>0) and has a stoichiometric ratio n of 3.5 to 3.8, a ratio of La to Re (x/y) of 3.5 or less, at least an A5B19 type structure, and an average C axis length α of crystal lattice of 30 to 41 Å.
