摘要： PROBLEM TO BE SOLVED: To provide a battery.SOLUTION: In a battery (1) comprising a can (11), a lid (12), and a seal (13), the lid (12) is adapted to the can (11) to assemble a housing in a closed inner capacity, and the seal (13) seals the lid (12) and the can (11) associated with each other. A porous film (14) is parallely arranged on principal faces of the can (11) and the lid (12), and splits the inner capacity into two sub-cells (15, 16). Each of the sub-cells (15, 16) includes one or more electrolyte layers, and one or more layer structures. The layer structure is provided with a conductive film at least partially covered with an active material, and including one or more through holes. Furthermore, the layer structure is arranged in parallel to the porous film (14), and the conductive film is connected to any of the can (11) and the lid (12). The structure allows a large contact area between the active material and the electrolyte, and between the electrolyte and the porous film.
