Summary:An energy storage device (battery) 1 includes an electrode assembly 20 having current correcting tabs 28, 29 each of which is formed of a plurality of projecting portions 24b, 26b projecting from a first straight line portion 20c on one side in a stacking direction of electrode sheets 21, 22. The electrode assembly 20 is housed in a case (exterior body) 10. The energy storage device further includes current collectors 60A, 60B which are electrically connected to the external terminals 50A, 50B disposed on the case 10. The current collectors 60A, 60B are connected to the current collecting tabs 28, 29 arranged in a stacking direction of the electrode sheets 21, 22 on a second straight line portion 20d side where the projecting portions 24b, 26b are not formed.
