PROBLEM TO BE SOLVED: To provide a method for producing an unsaturated carboxylic acid ester by performing a reaction of an unsaturated aldehyde with an alcohol in the presence of oxygen, stably maintaining a high unsaturated carboxylic acid ester production rate and a high unsaturated aldehyde conversion rate, and eliminating a risk of the damage of a reactor or the ignition of a catalyst. SOLUTION: This method for producing the unsaturated carboxylic ester by performing the reaction of the unsaturated aldehyde with the alcohol in the presence of oxygen is characterized by discharging the catalyst so that the remaining catalyst in the reactor becomes ≤3 wt.% based on the weight of the inputted catalyst.
