<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte solution battery with improved productivity through prevention of damage of a cathode due to winding, in winding a cathode plate with high cathode active material density. <P>SOLUTION: In the nonaqueous electrolyte solution battery made by housing an electrode plate group structured by winding an anode plate and a cathode plate with an electrode mixture coated on either face of a collector through a separator, and electrolyte solution in a case, the cathode is provided with a coated part covered with the electrode mixture and a non-coated part without coating of the electrode mixture and with the collector exposed. A lead for current collection is connected to the non-coated part, and an insulation tape is arranged at an interface part of the coated part and the non-coated part, with the insulation tape having a paste agent face existing only at one side end of the base material face, and pasted only to the non-coated part. <P>COPYRIGHT: (C)2008,JPO&INPIT |
