Abstract

A method of manufacturing a nonaqueous electrolyte secondary battery includes: a step of forming a first electrode mixture layer containing an electrode active material and a first binder; a step of forming granulated particles containing the electrode active material and a second binder; a step of forming a second electrode mixture layer, which is formed of the granulated particles, on the first electrode mixture layer; a step of forming a heat resistance layer, which contains an inorganic filler and a third binder, on a surface of a separator; a step of preparing an electrode body by laminating the electrode and the separator such that the second electrode mixture layer and the heat resistance layer are in contact with each other; and a step of heating the electrode body.
