The current collector includes a terminal connection part connected to the electrode terminal and an electrode assembly-connection part connected to the electrode assembly. The energy storage device further includes a spacer disposed lateral to the electrode assembly-connection part of the current collector. The spacer includes a restriction part configured to contact a part in a longitudinal direction of the electrode assembly-connection part of the current collector to restrict movement of the current collector in the longitudinal direction.
