Abstract
A secondary battery includes: a power generation element that charges and discharges; a battery case that houses the power generation element; and an electrode terminal that is exposed in an outer surface of the battery case and is electrically connected to the power generation element. The secondary battery includes a current cutoff mechanism and an auxiliary terminal. The current cutoff mechanism is disposed on a current path connecting between the power generation element and the electrode terminal inside the battery case and capable of cutting off an electric current. The auxiliary terminal is electrically connected to the current path positioned between the power generation element and the current cutoff mechanism of current paths and exposed in the outer surface of the battery case.
