PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery capable of exhibiting high capacity, small capacity drop accompanying the charging/discharging cycles, and capable of manufacturing in a simple process suitable for an industrial production. SOLUTION: A negative electrode is prepared by bonding metal particles, capable of electrochemically absorbing and releasing alkali metal ions or alkali metal atoms, having an average particle size of 1 μm or less, and a conductive material different from the metal particles, having an average particle size of 1 μm or less to a current collector with a binder. The metal particles are particles of at least one metal selected from among the group comprising Al, Si, Sn, Pb, As, Sb, Bi, Zn, Cd, Ag, Au, Pt, Pd, Mg, Na, and K. |
