PROBLEM TO BE SOLVED: To provide an industrial method for preparing ammonium peroxodisulfate and alkaline metal peroxodisulfate which is capable of completely omitting the use of accelerators and is implemented when an electrolysis is of low current density. SOLUTION: In the case of the method for preparing the peroxodisulfate, for example, ammonium peroxodisulfate, sodium peroxodisulfate and potassium peroxodisulfate by anodically oxidizing an electrolyte containing sulfate and/or hydrogensulfate, a diamond layer which is arranged on a conductive carrier and is made conductive by doping using a tervalent or pentavalent element is used as an anode and the accelerators are not added to an anolyte.
