Abstract
A current interrupting device of a sealed battery includes a conductive member that is electrically connected to an external terminal of a battery case; a collector terminal that is arranged inside the battery case; and a reversing plate that is interposed between the conductive member and the collector terminal, and that electrically cuts off the conductive member from the collector terminal by deforming in response to an increase in pressure inside the battery case. An inner peripheral surface of the conductive member is joined to an outer peripheral surface of the reversing plate. An upper surface of the reversing plate does not contact the conductive member regardless of an activation of the current interrupting device.
