Abstract
An electrode terminal component used in a power storage device including a power storage cell and a package member covering it includes: an electrode terminal made of metal, plate-shaped, and connected to the power storage cell to protrude out of the package member; and a heat-seal member made of resin, having a heat-sealing property with both the package member and the electrode terminal, and formed to surround a predetermined area on the top, bottom, and opposite side faces of the electrode terminal. A depression or elevation is formed in a predetermined area on the opposite side faces of the electrode terminal. The dimension in the electrode width direction of the depression or elevation formed on the opposite side faces of the electrode terminal is 0.1 mm or more.
