Abstract
In a titanium oxide compound according to the present invention, the titanium oxide compound is obtained by eluating potassium of potassium tetratitanate expressed by a general formula K2Ti4O9 and performing thermal processing, and, in an X-ray diffraction spectrum of the potassium tetratitanate obtained by using a Cu—Kα ray source, between a peak intensity Ia of a (200) plane, a peak intensity Ic of a (004) plane and a peak intensity Ib of a (31-3) plane, a relationship of Ia>Ib>Ic is satisfied.
