    • A dispersion in organic solvent of a core-shell type tetragonal titanium oxide solid solution in which a core is composed of a tetragonal titanium oxide microparticle containing at least one element (M 0 ) selected from the group consisting of gallium, vanadium, niobium, tantalum, zirconium, aluminum, and indium in the solid solution and containing tin in the solid solution, and a shell surrounding the core is composed of silicon oxide. The core-shell type solid solution has a particle diameter (D 50 ) corresponding to 50% in volume-based cumulative particle size distribution as measured by a dynamic light scattering method using a laser beam of up to 50 nm, the amount of the tin component dissolved in the solid solution, expressed in molar ratio (Ti/Sn) of titanium to tin, is in the range from 10 to 1,000, and the total amount of the (M 0 ) component dissolved in the solid solution, expressed in molar ratio (Ti/M 0 ) of titanium to (M 0 ), is in the range from 10 to 1,000.
