PROBLEM TO BE SOLVED: To provide a method for producing a carboxylic monoester in high selectivity by dehydrating esterification reaction between a polyhydric alcohol and a carboxylic acid while suppressing impurity carboxylic diester formation. SOLUTION: The method for producing the carboxylic monoester by dehydrating esterification reaction between the polyhydric alcohol and the carboxylic acid in the presence of a solid acid catalyst smaller than 200Åin average pore size, wherein water is made to exist in the reaction system at 70-1,000 mass% of the solid acid catalyst on a dry basis.
