Abstract
An energy storage device includes an electrode assembly, a container that contains the electrode assembly therein, a metallic cover member that closes the opening of the container and has a first fitting portion, and a current collector having a second fitting portion that is fitted to the first fitting portion in a fitted state. Thus, the compact energy storage device having a large capacity can suppress the positional deviation between the cover member and the current collector.
