<P>PROBLEM TO BE SOLVED: To provide a device for separation of water-oil emulsion, efficiently separating the water-oil emulsion with a simple operation at low cost, and having a long durability. Ž<P>SOLUTION: The device for separation of water-oil emulsion includes a separation tank containing water-oil emulsion, and at least one ultrasonic oscillation means set on a wall of the separation tank. The reflection wave of the ultrasonic wave oscillated from the ultrasonic oscillation means does not directly return to the ultrasonic oscillation means. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
