A resin composition having an appropriate viscosity suitable for sealing a light-emitting element, the cured product having a refractive index equal to or higher than that of an epoxy resin, excellent in heat resistance and light resistance, and thermal stress relaxation A resin composition having properties is provided. A curable resin composition contains a high refractive index acrylic monomer having a refractive index of 1.52 or more and a non-polymerizable carbazole, and further contains a polymerizable carbazole as necessary. As the high refractive index acrylic monomer, acrylate or methacrylate having a fluorene skeleton, bisphenol A skeleton, biphenyl skeleton, naphthalene skeleton or anthracene skeleton is used.
