PURPOSE:To make a substantial connection spot not to be hidden inside a through hole for enhancing reliability by connecting the conductive part of electrode plate arranged on each cell to each other with an intra-cell connection member pressed into the through hole. CONSTITUTION:A throughhole 2 is formed in a partition 4 dividing cells and an intra-cell connection member 3 is pressed into this throughhole 2. The throughhole 2 is positioned adjacent to the conductive parts 1, 1 of an electrode arranged inside each cell. And both ends of the member 3 are heated and melted respectively to be connected to the conductive parts 1 and 1. In this constitution, a substantial connection spot is not hidden inside the throughhole so as to have high reliability. Further, as the intra-cell connection member is pressed into the throughhole, intra-partition airtightness can be secured without providing any special structure. |
