Abstract

An electric cell comprises: a power generating element including electrodes; a cell container including a cell case for housing the power generating element and a cell cover for sealing an opening of the cell case; two external terminals disposed on the cell cover; and two collector electrodes for connecting the electrodes of the power generating element to the external terminals; wherein each of the external terminals includes: a connector connected to one of the collector electrodes within the cell container; a flat section located right above the connector and exposed to the outside of the the cell container; and a bolting section located adjacent to the flat section and having an insertion hole, and wherein the connector, the flat section, and the bolting section are integrally formed. The electric cell allows connection of external terminals to busbars by bolting or welding.
