摘要： A titanium oxide aerogel particle has absorption at wavelengths of 450 nm and 750 nm in a visible absorption spectrum, a surface to which a metal compound containing a metal atom and a hydrocarbon group is bonded via an oxygen atom, a BET specific surface area in a range of 120 m2/g to 1,000 m2/g, and a value A is in the range of 0.03 to 0.3. The value A is calculated by formula: A={(peak intensity of C—O bond+peak intensity of C═O bond)/(peak intensity of C—C bond+peak intensity of C═C bond)}. In the formula, the peak intensity is a value determined from a C 1s XPS spectrum.
