<p>[Problem] Operating a current interrupt mechanism which is positioned within a secondary battery results in electrical energy being left accumulated in the secondary battery. [Solution] A secondary battery comprises: a power generation element which carries out charging and discharging; a battery case which houses the power generation element; and an electrode element which is exposed on the outer face of the battery case and is electrically connected to the power generation element. The secondary battery further comprises a current interrupt mechanism and an auxiliary terminal. The current interrupt element is disposed within the battery case upon a current path which connects the power generation element and the electrode terminal, and is capable of interrupting the current. The auxiliary terminal is electrically connected within the current path at a location between the power generation element and the current interrupt mechanism, and is exposed on the outer face of the battery case.</p> |
