  "textContent": "In the case where a film, which has lower strength than a metal can, is used as an exterior body of a secondary battery, a current collector provided in a region surrounded by the exterior body, an active material layer provided on a surface of the current collector, or the like might be damaged when force is externally applied to the secondary battery. A secondary battery that is durable even when force is externally applied thereto is provided. A cushioning material is provided in a region surrounded by an exterior body of a secondary battery, Specifically, a cushioning material is provided on the periphery of a current collector such that a sealing portion of an exterior body (film) is located outside the cushioning material.",
