Disclosed is a sterilization apparatus using hydrogen peroxide, which comprises a housing which has a sterilization chamber for accommodating to-be-sterilized objects an evaporator connected with the sterilization chamber for supplying hydrogen peroxide vapor to the sterilization chamber for the purpose of sterilizing to-be-sterilized objects a hydrogen peroxide supply apparatus connected with the evaporator for the purpose of supplying liquid hydrogen peroxide to the evaporator an enrichment chamber connected with the evaporator for the purpose of evaporating moisture from the hydrogen peroxide supplied to the evaporator and sucking the evaporated moisture, thus enriching the hydrogen peroxide a vacuum pump connected with the enrichment chamber for the purpose of providing a vacuum pressure to the enrichment chamber a blower which includes a fan disposed in the interior of the sterilization chamber for forcibly flowing the air of the sterilization chamber and is a motor for driving the fan and a fan heater disposed in the interior of the sterilization chamber for the purpose heating the air flowing by means of the fan. The sterilization apparatus using hydrogen peroxide according to the present invention makes it possible to enrich the hydrogen peroxide using an enrichment chamber, and the sterilization power with respect to the to-be-sterilized objects can be enhanced.
