Abstract: A battery including an anode with an anode active material layer that includes anode active material particles made of an anode active material including at least one of silicon and tin as an element. 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 of the surface of each anode active material particle in contact with an electrolytic solution 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. The thickness of the oxide-containing film is preferably within a range from 0.1 nm to 500 nm both inclusive.
