PROBLEM TO BE SOLVED: To improve discharge characteristics and charge / discharge cycle characteristics in a non-aqueous electrolyte secondary battery using a positive electrode containing an olivine-type lithium-containing phosphate having a high electric resistance as a positive electrode active material. . A non-aqueous electrolyte secondary battery comprising a positive electrode 1 on which a positive electrode mixture layer including a positive electrode active material, a binder, and a conductive agent is formed, a negative electrode 2 and a non-aqueous electrolyte is provided. The positive electrode active material of the positive electrode mixture layer is represented by the general formula Li x MPO 4 (wherein M is at least one element selected from Co, Ni, Mn and Fe, and 0 <x <1.3 The olivine-type lithium-containing phosphate represented by the above condition) was used, and a mixture of bulk carbon and fibrous carbon was used as a conductive agent for the positive electrode mixture layer.
