Abstract
An electric storage device includes an electrode assembly, a case that includes a defining wall and houses the electrode assembly, a sealing member that is arranged on the defining wall, and a conductive member that is electrically connected to the electrode assembly, the conductive member being supported by the sealing member. At least a portion of the defining wall where the sealing member is arranged includes an aluminum-based metallic material. The sealing member includes a material that is softer than the material for the at least a portion of the defining wall where the sealing member is arranged. The sealing member includes polyphenylene sulfide (PPS) resin and an elastomer. The elastomer is contained in an amount of 2% to 20% by weight. The conductive member is crimped in such a manner that the sealing member is pressed against the defining wall.
