Abstract
An energy storage device includes: a core; and a wound body including, layered and wound around the core: a positive electrode, a negative electrode, and two separators, one of which is interposed between the positive electrode and the negative electrode and each having a first surface and a second surface. The first surface has thermal bonding properties superior to thermal bonding properties of the second surface, and at least one of the two separators is bonded to the core via the first surface thereof.
