Abstract
A non-aqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a non-aqueous electrolyte. The positive electrode includes a positive electrode current collector, a positive electrode active material layer on a part of a surface of the positive electrode current collector containing a positive electrode active material, and an insulating layer on other parts of the surface of the positive electrode current collector containing an inorganic filler. The negative electrode includes a negative electrode current collector, and a negative electrode active material layer on a part of a surface of the negative electrode current collector containing a negative electrode active material. The insulating layer includes a first insulating layer disposed along an end portion of the positive electrode active material layer, and a second insulating layer formed at a position separated from the first insulating layer and facing an end portion of the negative electrode active material layer.
