Abstract
Provided is a particle material that achieves excellent mechanical properties and optical properties when dispersed in a transparent resin material in order to solve the problem. In a case where primary particles having particle sizes in a certain range are formed into an aggregate, mechanical properties are enhanced while optical properties are maintained. The primary particles each have compositions different between the inside thereof and the surface thereof. Therefore, the optical properties to be obtained are easily controlled unlike an inorganic substance in which both of the compositions are mixed at an atomic level. The particle material of the present invention is an aggregate including primary particles in which a specific surface area. diameter is not less than 0.8 nm and not greater than 80 nm, the primary particles formed of an inorganic substance in which a composition of a surface and a composition of an inside are different.
