摘要： A silica-titania composite aerogel particle includes: a base particle including silicon and titanium whose element ratio Si/Ti is more than 0 and 6 or less; and a surface layer present on the base particle and including a metal compound having a metal atom and a hydrocarbon group. The silica-titania composite aerogel particle has absorption at wavelengths of 450 nm and 750 nm in a visible absorption spectrum, has a BET specific surface area in the range of 200 m2/g to 1,200 m2/g, and has a value A 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). The peak intensity is obtained from a C is XPS spectrum.
