[Problem] Provided is a non-aqueous electrolyte secondary battery, in which when using an aqueous binder as a binder for a negative electrode active material, the gas generated may be effectively exhausted from an electrode, and thus, even when using it for a long period of time, a decrease in battery capacity is low. [Solution] Disclosed is a non-aqueous electrolyte secondary battery having a power generating element enclosed within an outer casing, in which the power generating element includes a positive electrode obtained by forming a positive electrode active material layer on a surface of a positive electrode current collector, a negative electrode obtained by forming a negative electrode active material layer comprising an aqueous binder on a surface of a negative electrode current collector, a separator for maintaining an electrolytic solution, and a gas releasing means for releasing a gas generated within the power generating element to an extra space inside of the outer casing, and in which the ratio value (V 2 /V 1 ) of a volume V 2 of the extra space to a volume V 1 of pores included in the power generating element is 0.5 to 1.0.
