Abstract

See full text

Provided is an UFB generating apparatus and an UFB generating method capable of efficiently generating an UFB-containing liquid with high purity. To this end, the ultrafine bubble generating apparatus includes a pre-processing unit that performs predetermined pre-processing on a liquid W and a generating unit that generates ultrafine bubbles in the liquid on which the pre-processing is performed. The generating unit generates the ultrafine bubbles by causing a heating element, which is provided in the liquid on which the pre-processing is performed, to generate heat to generate film boiling on an interface between the liquid and the heating element.
