NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

The present disclosure aims to suppress, in a winding type electrode body in which a negative electrode lead is bonded to a winding start side end of a negative electrode collector, electrode plate deformation in association with charge/discharge cycles. A nonaqueous electrolyte secondary battery according to one aspect of the present disclosure includes a winding type electrode body (). A negative electrode () includes a negative electrode lead () bonded to a winding start side end of a negative electrode collector and is wound at least one turn from a winding-direction inner end so as not to face a positive electrode () with a separator () interposed therebetween. The negative electrode () includes an insulating tape () adhered to the negative electrode collector so as to straddle a surface of the negative electrode lead () in a winding direction.
