Zusammenfassung:In a nonaqueous electrolyte secondary battery, a separator includes a substrate, a first filler layer containing phosphate salt particles, and a second filler layer interposed between the substrate and the first filler layer and containing inorganic particles. The separator is disposed between a positive electrode and a negative electrode in such a manner that the first filler layer and the second filler layer are directed to the positive electrode side. Further, a resin layer is disposed between the positive electrode and the first filler layer.
