PROBLEM TO BE SOLVED: To provide a resin composition-molded product having high transparency, excellent light resistance and a low water absorption at the same time. SOLUTION: The resin composition comprises core/shell type semiconductor superfine particles having a number average particle diameter of 1-50 nm, composed of a core of a semiconductor crystal and a shell of an oxide of at least one element selected from aluminum, silicon, zirconium, tin, and antimony provided on the surface of the core, and has a light transmittance per 1 mm optical path length at the sodium D line wavelength of >=70% and a saturated water absorption, measured under the conditions of 60 deg.C and a relative humidity of 90% in accordance with the ASTM D570 provision, of <=0.4 wt.%. |
