PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery, with a collecting structure, having an internal resistance smaller than conventional and superior productivity. SOLUTION: The nonaqueous electrolyte secondary battery comprises a plurality of collecting tabs 3, led out of respective electrodes of a rolled electrode body 2, bound at their ends with each other and held into one U-shaped collecting member 4 caulked to the ends. The collecting member 4 has a U-shaped portion 42 and a screw portion 41, and the screw portion 41 is provided projecting, perpendicular to the surface of a plane part of the U-shaped portion 42 and an inner face of the planar part is provided with a protrusion and a recess. Power, generated by the rolled electrode body 2, is extracted from an electrode terminal 91 via the collecting member 4. |
