The present invention provides an efficient production method suitable to industrial-scale production not requiring column purification for adamantyl (meth)acrylates having an adamantane skeleton and useful as monomers for use for resins excellent in optical properties, etc. A method for producing adamantyl (meth)acrylates of formulae (3) and (4), includes a reaction step of reacting a compound of formula (1) with a (meth)acryloyl halide or a (meth)acrylic anhydride in a reaction solution to give a mixture of compounds of formulae (2) to (4), and a separation step of separating the mixture of compounds of formulae (2) to (4), wherein the separation step comprises an extraction step of extracting compounds of formulae (2) and (3) from the reaction solution with a mixed solvent of water and a polar organic solvent, thereby giving a water/polar organic solvent solution containing the compounds of formulae (2) and (3) and the mixed solvent, and a back-extraction step of back-extracting the compound of formula (3) from the water/polar organic solvent solution with a non-polar organic solvent:
