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.

Abstract: A battery includes a battery element, housing body, and valve device. The housing body includes at least one laminate and an interior space wherein the battery element is housed, a first housing portion covers the interior space from a first side in a thickness direction, and a second housing portion that covers the interior space from a second side opposite to the first side in the thickness direction. The valve device attaches to the housing body and makes the interior space communicate with an external space. A joined edge portion is formed in the housing body by the first and second housing portion being fused along respective peripheral edges. The valve device is between the first and second housing portion in the joined edge portion, and an inner end of the valve device protrudes from an inner edge of the joined edge portion toward the interior space.
