  "textContent": "A power storage device includes a stacked body and a sealing body for sealing a side surface of the stacked body. The sealing body includes a first seal portion welded to a first surface of a first current collector, a second seal portion welded to a second surface of a second current collector, a spacer sandwiched between the first seal portion and the second seal portion, and a welding portion formed by welding outer edge portions of each seal portion and the spacer positioned outside an outer edge of the current collector. The spacer includes a first liquid injection port communicating with an internal space. The welding portion includes a second liquid injection port communicating with the first liquid injection port. A thickness of the spacer is larger than each of a thickness of the first seal portion and a thickness of the second seal portion.",
