PURPOSE: A removing method of burrs is provided to reduce the defective rate, to improve the productivity, the efficiency and the accuracy and to remove a large amount of burrs with a small manpower by simply removing the burrs on a processed portion. CONSTITUTION: A plastic formed material(10) on the surface of water and a supersonic wave generator(20) in the upper part of the formed material are dipped in water. Supersonic waves are transmitted from the dipped supersonic wave generator. Burrs(10a) of the formed material are removed by generating bubbles(80) or the vibration of moisture(90) around the dipped formed material. The formed material is dipped from 10mm to 15mm from the surface of water. The supersonic wave generator transmits the supersonic waves for 1 second.
