Abstract: The invention provides an anode capable of improving battery characteristics such as cycle characteristics and a battery using it. An anode current collector is provided with an anode active material layer. The anode active material layer contains at least one from the group consisting of simple substances, alloys, and compounds of silicon or the like capable of forming an alloy with Li.
