摘要：
A non-aqueous electrolyte secondary battery obtained by the present invention is a non-aqueous electrolyte secondary battery including an electrode body having a positive electrode sheet and a negative electrode sheet 20 stacked via a separator sheet 40. A porous layer 42 having filler particles 44 and a binder is formed between the separator sheet 40 and at least one of the positive electrode sheet and the negative electrode sheet 20. The median value in the circularity distribution of the filler particles 44 contained in the porous layer 42 is 0.85 to 0.97.
