Abstract
Core-shell type metal oxide particles each include: a core containing metal oxide particles that have an average primary particle diameter of 3-100 nm; and a shell containing metal oxide particles that have an average primary particle diameter of 1-7 nm and that cover the core surfaces. The average primary particle diameters have a relationship of (metal oxide particles of the cores)>(metal oxide particles of the shells). When component (a) is titanium oxide and component (b) is a metal oxide other than titanium oxide, the cores are formed of particles including component (a) or a combination of component (a) and component (b), and the shells are formed of particles including component (b). The mass ratio of (metal oxide other than titanium oxide)/(titanium oxide) is in the range of 0.05-1.0.
