To provide a nonaqueous secondary battery which is high in capacity and superior in cycle characteristic.

A nonaqueous secondary battery, having a positive electrode 1, a negative electrode 2, and a nonaqueous electrolyte, includes two kinds of compounds, i.e., a compound into and out of which alkali metals move at least during charging and discharging, and a compound which includes the alkali metals and does not substantially participate in charging and discharging. The compound into and out of which the alkali metals move during charging and discharging includes at least alkali metals and elements belonging to 12, 13, or 14 Group (except carbon) in the periodic table, and the compound including the alkali metals and in not effect participating in charging and discharging includes the same alkali metals as those contained in the compound into and out of which the alkali metals move during charging and discharging and elements belonging to 15, 16, or 17 Group in the periodic table.
