摘要
In a generating method and a generator of mist or fine-bubble, with a simple and small configuration, application into a wide range kind of liquid is enabled, and generating stably the mist or the fine-bubbles or both is enabled. The generator (1) is provided with a piezoelectric substrate (2) which equips two or more comb-like electrodes (21) on a surface (S) and arranged so that the surface (S) may intersect the mutual interface (10a) of the gas and the liquid (10) and a part of piezoelectric substrate (2) is put in a liquid (10), and a surface acoustic wave W excited on the surface (S) with the electrode (21) is made to propagate along the surface (S) so that may exist in the upper and lower sides of an interface (10a). The surface acoustic wave (W) generates mist (M) in the gas side which is above the interface (10a), and generates fine-bubbles (B) in the liquid (10) side which is below the interface (10a). Since the mist (M) and the fine-bubbles (B) are generated with the surface acoustic wave (W), without being based on mechanical operation for generating a turning stream, the mist (M) and the fine-bubbles (B) can be stably generated in the simple and small configuration.
