Abstract
A power storage device includes a case lid with a terminal inserting hole, a current collecting terminal having a hole insertion portion inserted in the terminal inserting hole and an external connection portion placed on a front surface side of the case lid, and an insulating resin member integrally molded with the current collecting terminal and the case lid. The insulating resin member includes an outer-periphery-side insulating resin portion and a back-surface side insulating resin portion connecting the current collecting terminal and the case lid. The back-surface side insulating resin portion is formed with a hollow portion penetrating through a back surface of the back-surface side insulating resin portion to a back surface of the outer connecting portion. The back surface of the outer connecting portion is formed with an annular band-shaped sealing portion along the outer edge portion of the hollow portion.
