NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERIES

An object of the present disclosure is to provide a nonaqueous electrolyte secondary battery resistant to the occurrence of electrode plate deformation which can cause an internal short circuit. A nonaqueous electrolyte secondary battery according to an example embodiment of the present disclosure includes a wound electrode assembly including a positive electrode, a negative electrode and a separator, and a nonaqueous electrolyte. The separator is bonded to the positive electrode over a region from the end of the positive electrode on the coiling start side to a length corresponding to at least one loop in the winding direction.
