Method for producing nucleoside-5'-phosphate ester
 Nucleoside-5'-phosphate ester is produced inexpensively and efficiently by allowing an acid phosphatase, especially an acid phosphatase having a lowered phosphomonoesterase activity to act under a condition of pH 3.0 to 5.5 on a nucleoside and a phosphate group donor selected from the group consisting of polyphosphoric acid or a salt thereof, phenylphosphoric acid or a salt thereof, and carbamyl phosphate or a salt thereof to produce nucleoside-5'-phosphate ester, and collecting it.
