摘要： A method of producing a non-aqueous electrolyte secondary battery of the present invention includes the steps of: (1) producing a negative electrode precursor by applying a negative electrode slurry including graphite particles and a binder onto a negative electrode core material and drying the same to form a negative electrode material mixture layer; and (2) producing a negative electrode by compressing while heating the negative electrode precursor at a temperature at which the binder softens. In the step (2), a temperature at which the negative electrode precursor is heated and a force with which the negative electrode precursor is compressed are controlled such that the compressed negative electrode material mixture layer in the negative electrode includes 1.5 g or more of the graphite particles per 1 cm3 of the negative electrode material mixture layer, and that an average circular degree of the graphite particles maintains 70% or more of an average circular degree of graphite particles in the negative electrode precursor.
