An active material layer containing silicon as an element is provided on a current collector. An anode lead is bonded to the active material layer. At least part of a bond region between the anode lead and the active material layer is made of copper or an alloy containing copper. Thereby, the electrical resistance can be prevented from being increased even though the anode lead is bonded to the active material layer. The anode lead may be made of copper or an alloy containing copper. Otherwise, coating layer made of copper or an alloy containing copper may be provided on the surface of a base.
