PROBLEM TO BE SOLVED: To provide a battery having plural electrode bodies which are down- sized and light-weighted, and which can be produced at a low cost. SOLUTION: This battery is characterized that it has the plural electrode bodies 1 to possess both a positive electrode and a negative electrode, a battery container 3 consisting of a water permeability resistant material to air-tightly retain the plural electrode bodies 1 inside, and an insulating wall member 2 which is arranged inside of the battery container 3 and wherein plural battery cell chambers 21 to separately house the plural electrode bodies 1 to each other are composed of partitioned insulators. Because in the battery of the present invention the battery container to show the water permeability resistance and the insulating wall member to exert an electric insulation are not integrally formed, an enlargement of a size of the battery and an elevation of cost necessary for manufacturing can be suppressed.
