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 0
