A non-aqueous electrolyte secondary battery including electrode body having structure in which positive electrode and negative electrode are laminated with separator and non-aqueous electrolyte. The positive electrode includes positive electrode current collector, positive electrode active material layer which is disposed on positive electrode current collector and contains first positive electrode active material, and insulating layer which is disposed along one end of positive electrode active material layer in predetermined width direction, and contains inorganic filler and second positive electrode active material. The negative electrode includes negative electrode current collector, and negative electrode active material layer which is disposed on negative electrode current collector and contains negative electrode active material, in which length in width direction is longer than length of positive electrode active material layer in width direction, and negative electrode active material layer faces positive electrode active material layer and at least part of insulating layer.
