METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

A method for manufacturing a nonaqueous electrolyte secondary battery, when an electrode tab is provided at a longitudinal-direction end portion of an electrode located at a winding-start side of an electrode body, the method being capable of sufficiently reducing damage on a separator and the electrode in a process for manufacturing the electrode body. In a manufacturing step of one example of an embodiment, a negative electrode tab is bonded to a longitudinal-direction end portion of a negative electrode to be located at a winding-start side of an electrode body, the negative electrode tab is processed so that a width-direction central portion of the negative electrode tab at least bulges toward a winding-outer side of the electrode body, and while a gap is formed between the negative electrode tab and a winding core, a positive electrode, the negative electrode, and a separator are wound around the winding core.
