摘要： Provided is a curable resin composition which has excellent optical properties, heat resistance, transparency, low water absorbability, and mold release property in molding, and reduces the occurrence of a burr from a mold. Also provided are a cured product thereof and an optical material. The curable resin composition includes: a component (A): a soluble polyfunctional (meth)acrylic acid ester copolymer which is obtained by copolymerizing components including a monofunctional (meth) acrylic acid ester (a) having an alicyclic structure, a bifunctional (meth) acrylic acid ester (b), and 2,4-diphenyl-4-methyl-1-pentene (c), has a reactive (meth) acrylate group derived from (b) in a side chain and a structural unit derived from (c) at an end, has a Mw of 2,000 to 20, 000, and is soluble in an organic solvent; a component (B): a polyfunctional (meth)acrylate; and a component (C): an initiator, in which the blending amounts (weight ratio) of the respective components are as follows: (B)/(A)=5 to 250/100, and (C)/[(B)+(A)]=0.1 to 10/100.
