In a voltammetry employing an electrode with a diameter of 2 mm, vibrating at ultrasonic frequecy of 38 kHz and at an amplitude of 0.5 through 3μm<SUB>p-p</SUB>, acoustic streamings were investigated by the flow visualizing experiment and the analysis of a two-dimensional finite element method. The experiment revealed that a gas bubble was generated on the electrode surface at the amplitude above 0.7μm<SUB>p-p</SUB>, and the vibrating mode of the bubble played an important role in the acoustic streaming. These mechanisms were successfully simulated by the analysis assuming a vortex pair located on the electrode.
