An object of the present invention is to provide a process for purifying 2-methyladamantan-2-yl(meth)acrylate with high separation efficiency and an industrially advantageous preparation process of 2-methyladamantan-2-yl(meth)acrylate. The present invention pertains to a preparation process of 2-methyladamantan-2-yl(meth)acrylate which comprises reacting 2-methyleneadamantane and (meth)acrylic acid by an acid catalyst to obtain a reaction mixture, and then separating 2-methyleneadamantane from the reaction mixture to obtain 2-methyladamantan-2-yl(meth)acrylate, wherein the reaction mixture is distilled in the presence of an organic compound having a boiling point, under atmospheric pressure, of 150° C. or greater but not greater than 260° C.
