PROBLEM TO BE SOLVED: To efficiently produce high purity scyllo-inositol on an industrial scale. SOLUTION: To a mixed solution containing scyllo-inositol and a neutral sugar other than scyllo-inositol, boric acid and a metal salt that are two moles or more of dissolved scyllo-inositol in the mixed solution are added, and the mixed solution By adjusting the pH of the solution to 8.0 to 11.0, a scyllo-inositol / boric acid complex is formed, the complex is separated from the mixed solution, and the separated complex is dissolved in an acid to be dissolved in an acidic solution or suspension. A liquid is prepared, and scyllo-inositol is purified from the acidic solution or suspension by a purification method using an ion exchange resin or the like or a precipitation method using a water-soluble organic solvent.
