  "textContent": "The present disclosure provides a method for producing a nonaqueous electrolyte secondary battery that allows a nonaqueous electrolyte solution to permeate, reliably and in a short time, into a wound electrode body. The method for producing a nonaqueous electrolyte secondary battery disclosed herein includes at least a winding step of forming a wound electrode body, a terminal connection step of connecting an electrode terminal to the wound electrode body, and a sealing step of accommodating the wound electrode body inside a battery case, and thereafter sealing the battery case. The production method disclosed herein includes, between the winding step and the terminal connection step, a permeation step of immersing a wound electrode body 20 in a nonaqueous electrolyte solution 30, and repeatedly pressing and releasing the wound electrode body 20. In the permeation step, the space between electrodes in the wound electrode body 20 is repeatedly opened and blocked to elicit a pumping effect such that the nonaqueous electrolyte solution 30 is pumped into the wound electrode body 20. As a result, the nonaqueous electrolyte solution 30 can be caused to sufficiently permeate in a shorter time than in conventional methods.",
