Abstract
An ultrafine bubble generating apparatus and an ultrafine bubble generating method capable of efficiently generating an ultrafine bubble-containing liquid with high purity are provided. In order to this, a heating element provided in a liquid is caused to generate heat, and film boiling is made on an interface between the liquid and the heating element. A film boiling bubble is generated by the film boiling, and ultrafine bubbles are thus generated near the film boiling bubble.
