Provided is a non-aqueous electrolyte battery excellent in initial static characteristics and continuous charge characteristics. The non-aqueous electrolyte battery includes a pellet-shaped positive electrode, a pellet-shaped negative electrode, a separator interposed between the positive and negative electrodes, and a non-aqueous electrolyte. The positive electrode includes a positive electrode active material, aluminum powder, a conductive agent, and a binder. The positive electrode active material contains vanadium pentoxide. The positive electrode has a porosity of 35.6 to 45.4 vol %. The negative electrode includes a negative electrode active material containing silicon, a conductive agent, and a binder.
