Abstract
The present invention is a resin composition comprising a transparent resin, and modified inorganic particles obtained by surface-modifying inorganic particles with a modifier, the transparent resin having a saturated water absorption at 37° C. of 0.015 to 0.25 wt %, the inorganic particles having an average particle size of 20 nm or less, and having a refractive index larger than that of the transparent resin by 0.40 or more, a modification ratio of the modified inorganic particles being 15 to 40 wt %, and the modifier being a compound represented by the formula (1) below. Here, Rrepresents a hydrocarbon group having 12 to 18 carbon atoms, and X represents a functional group that forms a bond to the surface of the inorganic particles, or an atomic group that comprises the functional group. Also disclosed are a resin formed article and an optical part.R—X  (1)
