Abstract: Provided are an anode capable of preventing an increase in impedance and variations in characteristics and a battery using the anode. An anode active material layer includes at least one kind selected from the group consisting of simple substances, alloys and compounds of silicon and the like capable of forming an alloy with Li. The anode active material layer is formed by a vapor-phase deposition method or the like, and is alloyed with an anode current collector.
