PROBLEM TO BE SOLVED: To provide a hydrogen storage alloy electrode capable of leading out a large current and reduced in the possibility of short-circuiting. SOLUTION: In this method for manufacturing the hydrogen storage alloy electrode 2 having a base material exposing part 12 in a peripheral edge along a width-direction b by using as a base material 1 a punching metal provided line-likely with a nonperforated part 11 narrower than a perforated part 10 perforated with a large number of holes 100 along a longitudinal direction a, by providing on the base material 1 an electrode mix layer 20 using hydrogen storage alloy powder as an active material to generate the base material exposing part 12 containing no electrode mix layer in the nonperforated part 11, and by roll-pressed thereafter along the longitudinal direction a to be cut, a width y (mm) of the base material exposing part 12 satisfys expression (1); 1<=y<=-5t+4.75 (t<0.75) [t represents a thickness (mm) of the electrode after roll-pressed]. |
