It is the purpose of this paper to investigate the influences of ionic wind on the collecting water film in wet type electrostatic precipitator. In order to study this influences, behaviour of the water surface and the ionic wind were observed in needle or wire to water electrode. The results of these experiments may be summarized as follows. (1) The water surface is hollowed by the ionic wind pressure in needle to static water electrode. The depth and the diameter of this hollow is in proportion to corona current at a range of measurement. (2) The pressure of the ionic wind presses the flowing water film. It is considered that the pressure contribute to suppression of entrainment of the flowing water film. (3) The ionic wind stir up the water film. It is considered that this effect is one of the collecting forces.
