Abstract
A stack-type nonaqueous electrolyte secondary battery includes an electrode stack. The electrode stack is housed in an exterior body and includes a plurality of positive electrodes, a plurality of negative electrodes, and a separator. The positive electrodes and the negative electrodes are alternately arranged. The separator includes a fanfold portion including a plurality of intervening elements interposed between the positive electrodes and the negative electrodes. The separator includes a wrapper portion at a portion continuous with the fanfold portion. The wrapper portion extends out of the electrode stack and is disposed to cover at least part of a periphery of the electrode stack.
