Abstract: An energy storage device includes an electrode terminal, an electrode assembly, and a current collector connecting the electrode terminal and the electrode assembly. The current collector includes a terminal connecting portion connected to the electrode terminal, an electrode connecting portion connected to the electrode assembly in a first direction, and an intermediate portion that connects the terminal connecting portion and the electrode connecting portion. The intermediate portion is positioned at a position overlapping the terminal connecting portion when viewed in the first direction. The intermediate portion includes an intermediate portion first surface opposite to a surface facing the terminal connecting portion of the intermediate portion. The electrode connecting portion includes an electrode connecting portion first surface, at which the electrode assembly and the electrode connecting portion are connected, the electrode connecting portion first surface being shifted from the intermediate portion first surface in the first direction.
