Abstract
According to one embodiment, there is provided an active substance. The active substance includes particles of niobium titanium composite oxide and a phase including a carbon material. The niobium titanium composite oxide is represented by TiM1NbM2O. The phase is formed on at least a part of the surface of the particles. The carbon material shows, in a Raman chart obtained by Raman spectrometry, a G band observed at from 1530 to 1630 cmand a D band observed at from 1280 to 1380 cm. A ratio I/Ibetween a peak intensity Iof the G band and a peak intensity Iof the D band is from 0.8 to 1.2.
