PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte cell formed into flat shape while preventing a lowering of the strength of both current collectors, shortening the excessive part of a negative pole activator, enabled to remarkably improve an energy density per volume and per weight by shortening the length of a separator in the direction of winding. SOLUTION: The nonaqueous electrolyte cell, composed of an electricity generating element with such a structure that a positive pole activator 15 and a negative pole activator 16 are wound through a separator 17, has a both poles current collector 11 with three-layered structure composed of an insulation film 13, a positive pole current collector 12 fixer to one side of the insulation film 13, and a negative pole current collector 14 fixed to the other side of the insulation film 13, here, the positive pole activator 15 is applied on the positive pole current collector 12 and the negative pole activator 16 is applied on the negative pole current collector 14. |
