A negative electrode constituting a non-aqueous electrolyte secondary battery, which is an example of an embodiment, comprises a negative-electrode mixture layer including a negative-electrode active material and a binder agent. The negative electrode includes, as the binder agent, at least a polymer constituted by a constituent unit A represented by formula (1), a constituent unit B represented by formula (2), and a constituent unit C represented by formula (3). The molar ratio (l/m) of the constituent unit A to the constituent unit B is from 0.2 to 1.8.
