  "textContent": "A power storage device includes an electrode assembly where a positive electrode plate and a negative electrode plate are wound with a separator interposed between the positive electrode and negative electrode plates; and a positive electrode current collector joined to the positive electrode plate at an upper end of the electrode assembly in axial direction P. The positive electrode current collector includes a plate-shaped flange joined to the positive electrode plate at a face facing the positive electrode plate in axial direction P and a column with an adjustable length in axial direction P that protrudes from the flange toward an upper side in axial direction P.",
