Abstract: In a deburring device configured to remove burrs of the molded product through radiation of ultrasonic waves, a height of the storage tank is set to 1.25λ mm when a wavelength of an ultrasonic wave is set to λ mm. A frequency range of ultrasonic wave radiating means arranged on a bottom side of the washing water storage tank is set to from 18 KHz to 28 KHz, and power density is set to 2 W/cm2 or higher. Further, there is arranged oscillating means configured to allow the molded product immersed in the washing water to vertically move with a stroke of at least 1/2λ mm in a vertical direction. Further, an amount of dissolved oxygen in the washing water is set to 1 mg/litter or less, and a water temperature of the deburring washing water is set to from 4° C. to 8° C.
