According to one embodiment, an active material for a battery includes a titanium composite oxide. The titanium composite oxide contains a monoclinic β-type titanium composite oxide as its main phase and has a ratio (A2/A1) which is 0.4 or less, where A1 is an area intensity of a first peak existing in a frequency range of 105 cm−1 to 133 cm−1 and A2 is an area intensity of a second peak existing in a frequency range of 134 cm−1 to 154 cm−1 on a Raman spectrum measured using an argon laser having a wavelength of 514.5 nm.
