1. A power storage device comprising:
a can;
an electrode body housed in the can, the electrode body including electrode sheets; and
wherein
the electrode body has outer surfaces including a thickness-direction outside surface located outside in a thickness direction of the electrode sheets, and
the power storage device further comprises:
a movement restricting member placed in the can, the movement restricting member including:
an electrode-body bonding portion bonded to a fixing surface that is at least a part of the thickness-direction outside surface; and
a can fixing portion that extends from the electrode-body bonding portion and is fixed to the can to restrict movement of the electrode body in the can,
the can includes:
a can body having a bottomed tubular shape with an opening, the can body being configured to house the electrode and the movement restricting member; and
a can lid closing the opening of the can body, and
the can fixing portion of the movement restricting member extends from the electrode-body bonding portion toward a can corner defined by the can body and the can lid, and is fixed to the can body and the can lid in the can corner.
