The present invention provides a method for producing hydrogen peroxide including a step of oxidizing an activating solution containing organic solvent, anthraquinone having an alkyl substituent group, and tetrahydroanthraquinone having an alkyl substituent group after reduction so as to produce hydrogen peroxide, and a recovery step of activating solution of removing by-product inactive materials accompanying with producing of said hydrogen peroxide from said activating solution and recycling the activating solution with said inactive material being removed to the producing step of hydrogen peroxide. Said recovery step of activating solution has (i) a first distillation step of recovering said organic solution by a distillation performed in pressure equal to or lower than atmosphere, and (ii) a section distillation step of recovering said.anthraquinone and said tetrahydroanthraquinone by a distillation performed in a lower pressure at a temperature equal to or higher than 200 DEG C with a period equal to or longer than 1 hour.
