PROBLEM TO BE SOLVED: To provide a method for continuously producing carboxylic ester by reacting an aldehyde with an alcohol in the presence of oxygen and a catalyst, wherein a high aldehyde conversion and a high carboxylic ester selectivity are realized and the carboxylic ester is stably and continuously produced for a long term. SOLUTION: This method for continuously producing carboxylic ester comprises using two or more reactors in series and reacting the aldehyde with the alcohol in the presence of the oxygen and the catalyst, wherein the method is characterized by using at least one catalyst separator before the final reactor and at least one other catalyst separator at the outlet of the final reactor.
