A secondary cell has a hydrogen-storing alloy electrode as a
negative-electrode plate 26, and the electrode contains first
hydrogen-storing alloy particles 36 and second hydrogen-storing alloy
particles 37. The first hydrogen-storing alloy particles 36 has
composition expressed by general expression (I)
(La.sub.a1Ce.sub.b1Pr.sub.c1Nd.sub.d1(Al).sub.el).sub.1-xMg.sub.x(Ni.sub.-
1-y(T1).sub.y).sub.z, where A1 represents at least one element selected
from a group consisting of Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu,
Ca, Sr, Sc, Y, Ti, Zr and Hf; T1 represents at least one element selected
from a group consisting of V, Nb, Ta, Cr, Mo, Mn, Fe, Co, Al, Ga, Zn, Sn,
In, Cu, Si, P and B; a1, b1, c1, d1 and e1 are in the range of
