摘要：
An active material containing a monoclinic β-type titanium oxide or a monoclinic β-type titanium complex oxide. A carbonate ion is disposed on at least a part of a surface of the active material. The active material has a peak belonging to a carbonate ion in at least a. region of 1430±30 cm−1, 1500±30 cm−1 and 2350±30 cm −1 in an infrared diffuse reflection spectrum obtained using a Fourier transform infrared spectrophotometer.
