One aspect of the present invention is a nonaqueous electrolyte energy storage device including a positive electrode having a positive composite that contains a phosphorus atom and a lithium-transition metal composite oxide containing manganese, wherein, in a spectrum of the positive composite by X-ray photoelectron spectroscopy, a peak position for P2p is observed at 134.7 eV or less. Another aspect of the present invention is a method for producing a nonaqueous electrolyte energy storage device, the method including forming a positive electrode using a positive composite paste that contains a phosphorus oxo acid and a lithium-transition metal composite oxide containing manganese.",
