[0002] [Solving Means] Provided is a non-aqueous electrolyte secondary battery having a power generating element enclosed inside an outer casing, wherein the power generating element includes a positive electrode having a positive electrode active material layer formed on a surface of a positive electrode current collector, a negative electrode having a negative electrode active material layer containing an aqueous binder formed on a surface of a negative electrode current collector, and a separator holding an electrolyte solution, wherein the ratio value (V/V) of a volume Vof a residual space inside the outer casing to a volume Vof pores of the power generating element is 0.4 to 0.5, and the ratio value (L/V) of a volume L of the electrolyte solution injected to the outer casing to the volume Vof the residual space inside the outer casing is 0.6 to 0.8.",
