Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for purifying butyl acrylate by which the formation of an acid component by the purification is efficiently suppressed. SOLUTION: The method for obtaining the purified butyl acrylate by purifying the butyl acrylate obtained by reacting acrylic acid with butanol in the presence of an acid catalyst by using a product column 25 includes regulating the concentration of butyl β-butoxypropionate in the butyl acrylate fed to the product column 25 so as to be ≤6 mass%.
