Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a battery, a battery pack, an electronic apparatus, an electric vehicle, a power storage device, and an electric power system, in which deformation of the battery shape can be restrained.SOLUTION: The battery comprises a wound electrode body including a wound cathode and a wound anode and an outer package in which the wound electrode body is housed. The anode includes as an anode active material an alloy based anode material containing lithium and at least an element which can form an alloy. Between an end in the winding axis direction of the wound electrode body and the outer package, there is a structure to restrain expansion of the outer package.
