PROBLEM TO BE SOLVED: To provide an ultrasonic sterilizer which reduces a cost and effectively sterilizes an article to be processed. SOLUTION: The ultrasonic sterilizer includes a processing tank 31 for housing an ultrasound propagating medium, a supporting body 43 provided in the processing tank 31 for supporting the article to be processed, an oscillator unit which is provided in the processing tank 31 and is equipped with an ultrasonic transducer 93, a circuit for driving an ultrasonic transducer which drives the ultrasonic transducer 93 and generates ultrasound, a moving mechanism 57 for moving at least one of the supporting body 43 and the oscillator unit by keeping a distance between them constant, and an operational part for setting prescribed sterilizing conditions regulated by the produced amount of a hydroxy radical generated with the generation of ultrasound. Since the ultrasonic sterilizer prevents the article to be processed from having an irradiation irregularity of the ultrasound, the sterilizing efficiency of the article to be processed is increased.
