A nonaqueous secondary battery achieves a long life-time and a high capacity density by increasing the discharging capacity and extending the life-time of the negative electrode. The battery has a positive electrode and a negative electrode reversibly absorbing and discharging an alkaline metal and a nonaqueous electrolyte. The negative electrode is made of an inter-metallic compound containing at least one element selected from the group consisting of 4B group elements, P and Sb. The inter-metallic compound has any one of CaF2 type, ZnS type and AlLiSi type crystal structures. The CaF2 type structure is either an inverse-fluorite structure or a fluorite structure having a lattice constant larger than 6.36 .ANG..
