| description | PROBLEM TO BE SOLVED: To provide a secondary battery in which a plurality of leads are drawn out of the positive and negative electrodes of a rolled electrode body contained in a battery can to enable electric power generated by the rolled electrode body to be taken out of a pair of electrode terminal parts via the leads, the secondary battery having a current-path interrupting mechanism which does not limit current values during charge and discharge. SOLUTION: In the secondary battery, the plurality of leads 3 are connected to the electrode terminal parts via a connection device 5. The connection device 5 has the current-path interrupting mechanism which forms a current path between the plurality of leads 3 and the electrode terminal parts, and which interrupts the current path when pressure exceeding a certain value is applied to its input parts. A shaft member 6 which expands axially as temperature rises is disposed at the center of the rolled electrode body 2, with the ends of the shaft member 6 opposed to the input of the current-path interrupting mechanism. |
