The invention provides a battery achieving excellent battery
characteristics by using, as an anode active material, any of metal
elements and metalloid elements each of which can form an alloy with a
lithium, alloys of these elements, and compounds of these elements. Mesh
projections as a frame structure are formed on the surface on the side
facing an anode active material layer, of an anode collector. By the mesh
projections, expansion and contraction in the plane direction of the
anode active material layer is suppressed. Thus, pulverization, peeling,
and the like of the anode active material layer caused by expansion and
contraction thereof are prevented and the cycle characteristics are
improved.
