PROBLEM TO BE SOLVED: To provide a method for producing a (meth)acrylic ester useful as a raw material for a resin as a constituent component of a coating material, an adhesive, a pressure-sensitive adhesive, a resin for ink, a resist, a molding material, an optical material and the like, especially the raw material for a resin for the resist in good yield. SOLUTION: The method for producing the (meth)acrylic ester represented by formula (4) carries out the steps of an acid-adding step for producing a carboxylic acid adduct by adding a carboxylic acid to a compound represented by formula (1), an acid-removing step for removing the carboxylic acid, and an ester-interchanging step for interchanging esters between the carboxylic acid adduct and a (meth)acrylic ester in order. In another aspect, the method for producing the (meth)acrylic ester involves using an acid catalyst in the acid-adding step, and carrying out a cleaning step for removing the acid catalyst by cleaning a liquid after the acid-removing step before the ester-interchanging step.
