Abstract
A non-aqueous electrolyte secondary battery includes at least an electrode composite material layer, an intermediate layer, and an electrode current collector. Intermediate layer is interposed between electrode composite material layer and electrode current collector. Intermediate layer contains at least insulating particles and conductive particles. Each insulating particle has an arc shape in a cross section of intermediate layer along a thickness direction. More conductive particles are present on an outer-circumference side of each arc shape than on an inner-circumference side of the arc shape.
