Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ultrasonic cleaning device that effectively removes a contaminant such as a radiation substance from coarse particles and an ultrasonic cleaning method.SOLUTION: An ultrasonic cleaning device includes: a washing tank 11 for storing slurry M; an agitator 12 for mixing and agitating the slurry M stored in the washing tank 11 in a predetermined circulation direction in the washing tank 11; and an ultrasonic vibration element 13 for radiating an ultrasonic wave to the slurry M stored in the washing tank 11. A pollution substance is subjected to washing processing by setting an effective radiation range T of the ultrasonic wave so as to cross at least part of an agitation stream C almost at right angles to a circulation direction and radiating the ultrasonic wave to the slurry M.
