Provided is a nonaqueous electrolyte battery which is not significantly decreased in the battery performance even if a flameproofing agent layer is formed therein. As a positive electrode plate of a nonaqueous electrolyte battery, a positive electrode plate (3) is configured by forming a positive electrode active material layer on the front surface and/or the back surface of a positive electrode collector and by forming a flameproofing agent layer, which contains a cyclic phosphazene compound bound by a polyvinylidene fluoride, on the surface of the positive electrode active material layer. The content of the cyclic phosphazene compound is set to 3.5-7.5% by weight relative to the weight of the positive electrode active material layer, and the content of the polyvinylidene fluoride is set to 15-25% by weight relative to the weight of the cyclic phosphazene compound. |
