Abstract
A sealed battery includes a case, an internal terminal, an external terminal, and an insulating holder. The internal terminal of the sealed battery includes a current collector connected to the electrode body, a shaft portion exposed outside the case, and a riveted portion that is provided on an end of the shaft portion outside of the case and is pressure-deformed so as to extend along an upper surface of the external terminal. The insulating holder includes a heat resistant portion formed of an insulating material having higher heat resistance than other regions of the insulating holder and the heat resistant portion is disposed in contact with the external terminal at least below a boundary between the riveted portion and the external terminal.
