  • Publication number: 20230155260
    Abstract: An energy storage device includes an electrode body and an outer packaging. The outer packaging seals the electrode body. The outer packaging is constituted by a film-like outer packaging member. The outer packaging includes a first sealing portion sealed by joining surfaces that face each other in a state in which the outer packaging member is wrapped around the electrode body. A base portion of the first sealing portion is formed at the boundary between a first surface and a second surface of the outer packaging. The first surface has a larger area than the second surface. The first sealing portion does not overlap the first surface in a plan view.
