摘要

A curable resin composition which comprises (A) an epoxy resin having a silicone backbone and (B) an epoxy resin curing agent, optionally contains (C) a curing accelerator, and has such a property that a cured product thereof has a refractive index of 1.44 or more and less than 1.499 at 663 nm and 25˚C. It is preferred that the epoxy resin curing agent (B) is a polycarboxylic acid resin or a polycarboxylic acid.
