PROBLEM TO BE SOLVED: To provide a conveyance method, of an oily liquid, which can convey an upper layer oily liquid of a two-liquid layer structure of water/oil. SOLUTION: This conveyance method of an oily liquid is to apply ultrasonic vibration to act on a water layer and thereby, form a columnar form 16 of an oily liquid and convey the oily liquid after the separation of the water layer and an oily liquid layer. The conveyor 10 comprises a container 11 which stores the water layer and the oily liquid layer separated from the water layer and an ultrasonic vibrator 12 which generates ultrasonic vibration in the lower part of the water layer. The ultrasonic vibration is made to act on the water layer, and thereby, the columnar form 16 of the oily liquid is formed and the oily liquid is conveyed. COPYRIGHT: (C)2009,JPO&INPIT
