A non-aqueous electrolyte battery is provided that achieves an improvement in safety, particularly an improvement in tolerance of the battery to overcharging, and also prevents discharge capacity from degrading, without compromising conventional battery designs considerably. The non-aqueous electrolyte battery has a positive electrode including a positive electrode active material-layer stack and a positive electrode current collector, a negative electrode including a negative electrode active material layer, and a separator interposed between the electrodes. The positive electrode active material-layer stack has two layers respectively having different positive electrode active materials. Of the two layers, a first positive electrode active material layer ( 11 ) that is nearer the positive electrode current collector ( 16 ) contains an olivine-type lithium phosphate compound as its positive electrode active material and uses VGCF ( 18 ) as a conductivity enhancing agent.
