PROBLEM TO BE SOLVED: To provide a curable resin composition capable of efficiently producing a cured product which is excellent in heat resistance and transparency, and has a high refractive index, a high Abbe number and a thickness of 100 μm or more.SOLUTION: An optical curable resin composition contains: (A) a curable resin which has a reactive functional group (Fa) and is cured by reaction with the reactive functional group (Fa); (B) surface-modified nanoparticles which are metal oxide nanoparticles having a refractive index higher than that of a cured product of the curable resin (A), and have the surface modified with a reactive functional group (Fb) of a reaction mechanism different from the reaction of the reactive functional group (Fa); and (C) a first curing agent that starts the reaction of the curable resin (A).SELECTED DRAWING: None 【課題】 耐熱性及び透明性に優れ、且つ高屈折率、高アッベ数の厚み１００μｍ以上の硬化物を効率よく生産することができる硬化性樹脂組成物を提供する。【解決手段】 （Ａ）反応性官能基（Ｆａ）を有し、当該反応性官能基（Ｆａ）が反応して硬化する硬化性樹脂；（Ｂ）前記硬化性樹脂（Ａ）の硬化物よりも高い屈折率を有する金属酸化物ナノ粒子であって、表面が前記反応性官能基（Ｆａ）反応と異なる反応機構の反応性官能基（Ｆｂ）で修飾されている表面修飾ナノ粒子；及び（Ｃ）前記硬化性樹脂（Ａ）の反応を開始させる第１の硬化剤を含有する光学用硬化性樹脂組成物。【選択図】 なし
