  "textContent": "The purpose of the present disclosure is to more reliably interrupt the current path of a battery when an abnormality occurs in the battery and the internal pressure of the battery case rises. A sealed battery, which is an exemplary embodiment, comprises a battery case including a bottomed cylindrical outer can and a sealing body that closes an opening of the outer can, a gasket disposed between the outer can and the sealing body, and an electrode body including an electrode and housed in the battery case. The sealing body includes a metal plate, and the metal plate has a thin portion formed in an annular shape, a valve portion having a convex shape inside the battery case, and an annular portion to which the electrode lead is connected. The gasket is provided with an elastically deformable portion that abuts against the inner surface of the valve portion and urges the valve portion to the outside of the battery case.",
