PROBLEM TO BE SOLVED: To provide a preparation method for 3-methyl-2-butenyl acetate low in impurities. SOLUTION: In the preparation method for purified 3-methyl-2-butenyl acetate, crude 3-methyl-2-butenyl acetate is subjected to step (A) and/or (B). In step (A), the crude 3-methyl-2-butenyl acetate is treated with an aqueous solution of an alkali metal hydrogen sulfite, an organic layer is recovered, and 3-methyl-2-butenyl acetate is recovered from the organic layer. In step (B), the crude 3-methyl-2-butenyl acetate is treated with an aqueous solution of a base, an organic layer is recovered, and 3-methyl-2-butenyl acetate is recovered from the organic layer.
