According to one embodiment, a nonaqueous electrolyte battery includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. The positive electrode includes positive electrode active material secondary particles and a layer. An average secondary particle size of the positive electrode active material secondary particles is from 3 μm to 25 μm. The layer covers at least a portion of surfaces of the positive electrode active material secondary particles. The layer contains a lithium titanium oxide and has a thickness of 3 nm to 30 nm. A shortest distance between the positive electrode and the negative electrode is 12 μm or less.
