Abstract
According to one embodiment, an active material is provided. The active material includes a primary particle including an NbTiOphase and at least one Nb-rich phase selected from an NbTiOphase and an NbTiOphase. In the primary particle, a ratio M/Mof substance amount of niobium to titanium satisfies 5.0<M/M≤24.0. A diffraction chart according to a wide angle X-ray diffraction method using a CuKα ray for the active material includes a peak A and a peak C attributed to the NbTiOphase and a peak B appearing within a range of 2θ of 25.5±0.2° attributed to the Nb-rich phase. The active material satisfies a peak intensity ratio represented by 0<I/I<5.0. A half width of the peak C is in a range of 0.15° or more and 0.80° or less.
