An anode and a battery capable of improving battery characteristics such as cycle characteristics are provided. A coating containing at least one from the group consisting of oligomers having a polyene structure and derivatives thereof is provided on the surface of an anode active material layer. The anode active material layer contains a substance containing Si or Sn as an element as an anode active material. By the coating, oxidation of the anode active material layer is inhibited, and decomposition reaction of the electrolytic solution is inhibited.
