Abstract
A non-aqueous electrolyte secondary battery of the invention has a power generating element with a single-cell layer which comprises a positive electrode including a positive electrode active material layer formed on a surface of a positive electrode collector, a negative electrode including a negative electrode active material layer formed on a surface of a negative electrode collector and a separator disposed between the positive electrode the negative electrode and containing a non-aqueous electrolyte, in which a value RA (=Rzjis (2)/Rzjis(1)) for the ratio between the surface roughness (Rzjis(1)) of the surface of the negative electrode active material layer on the side in contact with the separator and the surface roughness (Rzjis(2)) of the surface of the separator on the side in contact with the negative electrode active material layer is 0.15 to 0.85.
