Abstract

A resin composition (X), which is a curable resin composition according to the present invention, contains a curable resin component (), a surface-modified nanodiamond (), and an organic medium. The surface-modified nanodiamond () includes a ND particle (), which is a nanodiamond particle, and a silane coupling agent (). The silane coupling agent () has a (meth)acryloyl-containing organic chain and is bonded to the ND particle (). The resin composition (X) is suitable for forming a nanodiamond-dispersed cured resin portion having both high transparency and high scratch resistance. An optical element according to the present invention has a light-transmitting region and includes a cured resin portion, which is a cured product of the resin composition (X), in at least part of the light-transmitting region. The optical element is advantageous for actually providing an optical element including a cured resin portion or cured resin layer having both high transparency and high scratch resistance.
