<P>PROBLEM TO BE SOLVED: To provide a resin molded product which is excellent in the external appearance and does not greatly degrade the mechanical strengths, by dispersing very suitably oxide fine particles with a high refractive index into a resin by means of a high general-purpose molding technique. Ž<P>SOLUTION: This resin molded product is obtained by using a porous oxide in which oxide primary particles form a praying beads-like arrangement that suppresses a contacting area of the particles with each other, and which has air-space formed by the oxide primary particles, and by crushing a part of or the whole porous oxide into the oxide primary particles when mixing with a transparent resin so that the oxide primary particles are nano-dispersed into the resin. The nano-dispersion prevents the cloudiness caused by an additive and improves the glossiness of the resin molded product owing to the oxide fine particles having a high refractive-index. Also, the mechanical strengths are not degraded even the additive amount is large. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
