[Solving Means] Provided is a non-aqueous electrolyte secondary battery which includes a power generating element including a positive electrode obtained by forming a positive electrode active material layer on the surface of a positive electrode current collector, a negative electrode obtained by forming a negative electrode active material layer on the surface of a negative electrode current collector, and a separator, in which the negative electrode active material layer contains an aqueous binder, a highly porous layer having a porosity that is higher than that of the separator is provided between the negative electrode active material layer and the separator, the porosity of the highly porous layer being from 50 to 90%, and a ratio of a thickness of the highly porous layer to a thickness of the negative electrode active material layer being from 0.01 to 0.4.",
