Curable resin composition

A resin composition having a viscosity suitable for encapsulating optical devices such as light-emitting devices is provided. Specifically, the cured product of the resin composition has a refractive index greater than or equal to that of epoxy resins, exhibits excellent heat resistance and light resistance, and has thermal stress relaxation properties. The curable resin composition contains a fluorene group-containing acrylate or methacrylate represented by the following formula and a specific monofunctional acrylate or methacrylate: wherein X is -(CH 2 CH 2 O) n - or -(CH 2 CH 2 O) n -CH 2 CH(OH)CH 2 O- with n being 1 to 5 and R is an acrylic or methacrylic group.
