Abstract:
A load applied to a portion to which an extraction electrode is attached is reduced. Disclosed is a cell including: a closed-end tubular case for accommodating a power generation element; a lid for the case; a terminal electrode disposed outside of the case and used for connection with another cell; an extraction electrode passing through the lid and used to extract power of the power generation element to the outside of the case; and a stepped connection electrode disposed outside of the case, the stepped connection electrode having a first flat portion to which the terminal electrode is connected and a second flat portion which is located at a level different from the level of the first flat portion and to which the extraction electrode is connected. The first and second flat portions have regions overlapping each other as viewed in a direction orthogonal to the thickness of the first and second flat portions.
