摘要： Sheet-shaped mixture layers are placed on both sides of a current collector to form an electrode (positive electrode) with a layered structure. The electrode with a layered structure and a counter electrode (negative electrode) thereof are wound via a separator, while a positional shift in a winding direction is caused between the current collector and the sheet-shaped mixture layers of the electrode with the layered structure, whereby a winding body is formed. The winding body is placed in a battery case (outer can) to constitute a battery. Particularly, in the electrode with a layered structure, by forming the current collector of a plain-woven wire net, a metal foil, expanded metal, a lath, or punching metal, a battery with satisfactory productivity suitable for an intermediate load can be provided at a low cost.
