Zusammenfassung:PURPOSE:To prevent internal short circuit in a battery and to increase the capacity of the battery by using a conductive sealing plate, which serves as a terminal having the other polarily and is used for sealing a container. CONSTITUTION:A current collecting plate 22 is placed on the bottom of a container 21 which serves as a terminal of one polarity, then an insulating plate 23 having a slit 24 is placed on the current collecting plate 22. Either one of positive and negative plates 28, 29 which are a power generating element 26 is inserted into the slit 24 to bring the bottom of the plate into contact with the current collecting plate 22. This plate is electrically connected to the container 21 through the current collecting plate 22. A gasket 30 having a slit 24 in its bottom is placed on the power generating element 26, and the other plate is inserted into the slit 24 of the gasket 30, and a current collecting plate 22 is placed thereon to electrically connect the upper part of the plate to the sealing plate 35 which serves as a terminal of other polarity through the current collecting plate 22. Internal short circuit in a battery is prevented, the filling ratio in the plate is increased, and the capacity of the battery is also increased.
