Provided are: a resin composition for optical components, which provides a cured product that has high pencil hardness comparable to that of glass, while having excellent bending strength and excellent mold releasability suitable for molding; and an optical component such as a resin lens, which is obtained by molding the composition. The present invention is a resin composition for optical components, which contains: 15-65 parts by weight of a ladder and/or random silsesquioxane derivative (a) having a 2-(3,4-epoxycyclohexyl)ethyl group and a weight average molecular weight of 2,000-10,000, said silsesquioxane derivative (a) being a hydrolysis-condensation product of a trialkoxysilane having a 2-(3,4-epoxycyclohexyl)ethyl group; an alicyclic skeleton-containing epoxy resin (b) in such an amount that the total of this component and the component (a) is 100 parts by weight; and 0.01-5 parts by weight of a curing agent. |
