An oxide-containing film including an oxide of at least one kind selected from the group consisting of silicon, germanium and tin is formed in a region in contact with an electrolytic solution of the surface of each anode active material particle by a liquid-phase method such as a liquid-phase deposition method. The region in contact with the electrolytic solution of the surface of each anode active material particle is covered with the oxide-containing film, thereby the chemical stability of the anode 22 is improved, and charge-discharge efficiency is improved. The thickness of the oxide-containing film is preferably within a range from 0.1 nm to 500 nm both inclusive.
