Zusammenfassung:	The invention provides a method for producing a peroxymonosulfuric acid solution with high stability, including the steps of mixing 35 mass% or more of hydrogen peroxide and 70 mass% or more of sulfuric acid to react them, cooling the reaction solution to 80°C or lower within five minutes after initiation of the mixing step, and diluting the reaction solution with water four times or more as much as the reaction solution by mass.
