摘要： [Object] To produce a (meth)acrylate copolymer useful as a photocurable resin composition at a temperature favorable to industrial production in a short time. [Solution] There is provided a method for producing a (meth)acrylate copolymer (X), including anionic polymerization of a mixture of a di(meth)acrylate represented by the following general formula (1) and an alkyl (meth)acrylate represented by the following general formula (2) in the presence of an organolithium compound (L), a tertiary organoaluminum compound (A) having a chemical structure represented by the general formula Al-O-Ar (wherein Ar denotes an aromatic ring) in its molecules, and at least one Lewis base (B) selected from the group consisting of ethers and tertiary polyamines. (wherein R 1 denotes a hydrogen atom or a methyl group, R 2 denotes a linear alkylene group having 1 to 5 carbon atoms, and R 3 and R 4 each independently denote a hydrocarbon group having 1 to 6 carbon atoms) (wherein R 5 denotes a hydrogen atom or a methyl group, and R 6 denotes an alkyl group having 1 to 6 carbon atoms)
