PROBLEM TO BE SOLVED: To provide a method for measuring phosphoric acid over a wide concentration range from low concentration to high concentration. SOLUTION: In measuring phosphoric acid by the use of an enzyme cycling system by using a dehydrogenase, together with a thio-NADP, a thio-NAD, a reduced thio-NADP or a reduced thio-NAD as a coenzyme, phosphoric acid is measurable over a wide concentration range, from low concentration to high concentration by measuring phosphoric acid, after previously removing free phosphoric acid in the reagent components for the measurement.
